Hello all, Canvas is starting soon, would you be interested to represent our community?
Last year I prepared a pixel art version of Carpenter Brut's logo, but it was too late unfortunately. Although we managed to draw a nice render of the community's logo !
Would you be interested to join me early on to draw the Carpenter Brut logo over the weekend ?
Merci d'avoir partagé cet article très intéressant !
Still odd, I very much doubt they use a 8bit variable to set this limit. What would this bring ?
Most people connected to the Internet today have never owned a desktop computer nor an HDD. A crazy amount of people have been introduced to computing with smartphones.
AI technologie could be nice. LLM and Diffusion models ruining the Internet with fake information and Fake art, being over hyped as AI that will change the world, all while burning up unimaginable amounts of energy? Yeah, I also hope it goes away.
Who's brave enough to ride the dickwave around the world ?!
I think you're right: https://www.imdb.com/title/tt11639414
Looks like an interesting show !
When I saw the signatures shooting up, I was worried about this kind of stuff.
Best time for Europeans to buy US goods ! /s
Hopefully this is secure throughout. I voted a while ago, I don't remember exactly the process.
I really hope we don't have some idiot who thought this would be a good idea to spam the system with some fake signatures, somehow.
Anyhow, let's go ! We can do it !
That raises the question: it is better to do sustainable foresting or hemp farming ?
No doubt that chopping down entire forest is terrible and for sure it's being done, Amazonian rain-forest comes to mind. I hope this stops.
Another interesting fact I've learned from my short time working in the paper industry: biggest growing demands are for 1. Toilet paper, 2. Packaging, while demand for printing paper is steadily decreasing.
Hmmm... I'm by no mean an expert on the matter, but I see how this would have a big negative environmental impact.
You usually don't cut down all the trees in your forest all at once to make paper. At least this is not how it's done in Europe and it is illegal to do that. Trees are selected in the forest either for paper or for lumber. Young trees are usually used for paper and to make space for older trees to keep growing until they can be use for lumber, planks and such.
Mission: annoy the enemy while they are trying to sleep.


Hello all, Recently Firefox 137 was announces with the addition of HEVC playback with hardware acceleration support for Linux. I am using Firefox 137 installed via DNF on Fedora 41, but if I try to play HEVC video for example from my Jellyfin, it will have to transcode, if I go try this test sample it straight up not play, so what's up with that ? Playing content with mpv will work just fine. Firefox also reports HEVC decoding as supported. Same result with both my desktop with AMD iGPU and dGPU, as well as my laptop with just Intel iGPU.

Hello all,
This is a follow-up from my previous post: Is it a good idea to purchase refurbished HDDs off Amazon ?
In this post I will give you my experience purchasing refurbished hard drives and upgrading my BTRFS RAID10 arrray by swaping all the 4 drives.
TL;DR: All 4 drives work fine. I was able to replace the drives in my array one at a time using an USB enclosure for the data transfer !
1. Purchasing & Unboxing
After reading the reply from my previous post, I ended up purchasing 4x WD Ultrastar DC HC520 12TB hard drives from Ebay (Germany). The delivery was pretty fast, I received the package within 2 days. The drive where very well packed by the seller, in a special styrofoam tray and anti-static bags !packaging
2. Sanity check
I connect the drives to a spare computer I have and spin-up an Ubuntu Live USB to run a S.MA.R.T check and read the values. SMART checks and data are available from GNOME Disks (gnome-disk-utility), if you don't want to bother with the terminal.
All the 4 disks passed the self check, I even did a complete check on 2 of them overnight and they both passed without any error.
More surprisingly, all the 4 disks report Power-ON Hours=N/A
or 0
. I don't think it means they are brand new, I suspect the values have been erased by the reseller.
!smart data
3. Backup everything !
I've selected one of the 12TB drives and installed it inside an external USB3 enclosure. On my PC I formatted the drive to BTRFS with one partition with the entire capacity of the disk.
I then connected the, now external, drive to the NAS and transfer the entirety of my files (excluding a couple of things I don't need for sure), using rsync
:
bash rsync -av --progress --exclude 'lost+found' --exclude 'quarantine' --exclude '.snapshots' /mnt/volume1/* /media/Backup_2024-10-12.btrfs --log-file=~/rsync_backup_20241012.log
Actually, I wanted to run the command detached, so I used the at command at (not sure if this is the best method to do this, feel free to propose some alternatives):
bash echo "rsync -av --progress --exclude 'lost+found' --exclude 'quarantine' --exclude '.snapshots' /mnt/volume1/* /media/Backup_2024-10-12.btrfs --log-file=~/rsync_backup_20241012.log" | at 23:32
The total volume of the data is 7.6TiB, the transfer took 19 hours to complete.
4. Replacing the drives
My RAID10 array, a.k.a volume1 is comprise of the disks sda, sdb, sdc and sdd, all of which are 6TB drives. My NAS has only 4x SATA ports and all of them are occupied (volume2 is an SSD connected via USB3).
bash m4nas:~:% lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 1 5.5T 0 disk /mnt/volume1 sdb 8:16 1 5.5T 0 disk sdc 8:32 1 5.5T 0 disk sdd 8:48 1 5.5T 0 disk sde 8:64 0 111.8G 0 disk └─sde1 8:65 0 111.8G 0 part /mnt/volume2 sdf 8:80 0 10.9T 0 disk mmcblk2 179:0 0 58.2G 0 disk └─mmcblk2p1 179:1 0 57.6G 0 part / mmcblk2boot0 179:32 0 4M 1 disk mmcblk2boot1 179:64 0 4M 1 disk zram0 252:0 0 1.9G 0 disk [SWAP]
According to documentation I could find (btrfs replace - readthedocs.io, Btrfs, replace a disk - tnonline.net), the best course of action is definitely to use the builtin BTRFS command replace
.
From there, there are 2 method I can use:
- Connect new drive, one by one, via USB3 to run
replace
, then swap the disks in the drive-bay - Degraded mode, swap the disks one by one in the drive-bays and rebuild the array
Method #1 seems to me faster and safer, and I've decided to tried this one first. If it doesn't work, I can fallback to method #2 (which I had to for one of the disks !).
4.a. Replace the disks one-by-one via USB
!NAS setup with external drive
I've installed a blank 12TB disk in my USB enclosure and mounted it to the NAS. It is showing as sdf
.
Now, it's time to run the replace
command as described here: Btrfs, Replacing a disk, Replacing a disk in a RAID array
bash sudo btrfs replace start 1 /dev/sdf /mnt/volume1
We can see the new disk is shown as ID 0 while the replace operation takes place:
```bash m4nas:~:% btrfs filesystem show Label: 'volume1' uuid: 543e5c4f-4012-4204-bf28-1e4e651ce2e8 Total devices 4 FS bytes used 7.51TiB devid 0 size 5.46TiB used 3.77TiB path /dev/sdf devid 1 size 5.46TiB used 3.77TiB path /dev/sda devid 2 size 5.46TiB used 3.77TiB path /dev/sdb devid 3 size 5.46TiB used 3.77TiB path /dev/sdc devid 4 size 5.46TiB used 3.77TiB path /dev/sdd
Label: 'ssd1' uuid: 0b28580f-4a85-4650-a989-763c53934241 Total devices 1 FS bytes used 46.78GiB devid 1 size 111.76GiB used 111.76GiB path /dev/sde1 ```
It took around 15 hours to replace the disk. After it's done, I've got this:
```bash m4nas:~:% sudo btrfs replace status /mnt/volume1 Started on 19.Oct 12:22:03, finished on 20.Oct 03:05:48, 0 write errs, 0 uncorr. read errs m4nas:~:% btrfs filesystem show Label: 'volume1' uuid: 543e5c4f-4012-4204-bf28-1e4e651ce2e8 Total devices 4 FS bytes used 7.51TiB devid 1 size 5.46TiB used 3.77TiB path /dev/sdf devid 2 size 5.46TiB used 3.77TiB path /dev/sdb devid 3 size 5.46TiB used 3.77TiB path /dev/sdc devid 4 size 5.46TiB used 3.77TiB path /dev/sdd
Label: 'ssd1' uuid: 0b28580f-4a85-4650-a989-763c53934241 Total devices 1 FS bytes used 15.65GiB devid 1 size 111.76GiB used 111.76GiB path /dev/sde1 ```
In the end, the swap from USB to SATA worked perfectly !
```bash m4nas:~:% lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 111.8G 0 disk └─sda1 8:1 0 111.8G 0 part /mnt/volume2 sdb 8:16 1 10.9T 0 disk /mnt/volume1 sdc 8:32 1 5.5T 0 disk sdd 8:48 1 5.5T 0 disk sde 8:64 1 5.5T 0 disk mmcblk2 179:0 0 58.2G 0 disk └─mmcblk2p1 179:1 0 57.6G 0 part / mmcblk2boot0 179:32 0 4M 1 disk mmcblk2boot1 179:64 0 4M 1 disk zram0 252:0 0 1.9G 0 disk [SWAP] zram1 252:1 0 50M 0 disk /var/log m4nas:~:% btrfs filesystem show Label: 'volume1' uuid: 543e5c4f-4012-4204-bf28-1e4e651ce2e8 Total devices 4 FS bytes used 7.51TiB devid 1 size 5.46TiB used 3.77TiB path /dev/sdb devid 2 size 5.46TiB used 3.77TiB path /dev/sdc devid 3 size 5.46TiB used 3.77TiB path /dev/sdd devid 4 size 5.46TiB used 3.77TiB path /dev/sde
Label: 'ssd1' uuid: 0b28580f-4a85-4650-a989-763c53934241
Total devices 1 FS bytes used 13.36GiB
devid 1 size 111.76GiB used 89.76GiB path /dev/sda1
```
Note that I haven't expended the partition to 12TB yet, I will do this once all the disks are replace.
The replace operation has to be repeated 3 more times, taking great attention each time to select the correct disk ID (2, 3 and 4) and replacement device (e.g: /dev/sdf
).
4.b. Issue with replacing disk 2
While replacing disk 2, a problem occurred. The replace operation stopped progressing, despite not reporting any errors. After waiting couple of hours and confirming it was stuck, I decided to do something reckless that cause me a great deal of troubles later: To kick-start the replace operation, I unplugged the power from the USB enclosure and plugged it back in (DO NOT DO THAT !), It seemed to work and the transfer started to progress again. But once completed, the RAID array was broken and the NAS wouldn't boot anymore. (I will only talk about the things relevant to the disk replacement and will skip all the stupid things I did to make the situation worst, it took me a good 3 days to recover and get back on track...).
I had to forget and remove from the RAID array, both the drive ID=2 (the drive getting replaced) and ID=0 (the 'new' drive) in order to mount the array in degraded mode and start over the replace operation with the method #2. In the end it worked, and the 12TB drive is fully functional. I suppose the USB enclosure is not the most reliable, but the next 2 replacement worked just find like the first one.
What I should have done: abort the replace operation, and start over.
4.c. Extend volume to complete drives
Now that all 4 of my drives are upgraded to 12TB in my RAID array, I extend the filesystem to use all of the available space:
bash sudo btrfs filesystem resize 1:max /mnt/volume1 sudo btrfs filesystem resize 2:max /mnt/volume1 sudo btrfs filesystem resize 3:max /mnt/volume1 sudo btrfs filesystem resize 4:max /mnt/volume1
5. Always keep a full backup !
Earlier, I mentioned using one of the 'new' 12TB drive as a backup of my data. Before I use it in the NAS, and therefore erase this backup, I assembled 2 of the old drives into my spare computer and once again did a full copy of my NAS data using rsync
over the network. This took a long while again, but I wouldn't skip this step !
6. Conclusion: what did I learn ?
- Buying and using refurbished drives was very easy and the savings are great ! I saved approximately 40% compared to the new price. Only time will tell if this was a good deal. I hope to get at least 4 more years out of these drives. That's my goal at least...
- Replacing HDDs via a USB3 enclosure is possible with BTRFS, it works 3 time out of 4 ! 😭
- Serial debug is my new best friend ! This part, I didn't detail in this post. Let's say my NAS is somewhat exotic NanoPi M4V2, I couldn't have unborked my system without a functioning UART adapter, and the one I already had in hand didn't work correctly. I had to buy a new one. And all the things I did (blindly) to try fixing my system were pointless and wrong.
I hope this post can be useful to someone in the future, or at least was interesting to some of you !

I see some fairly interesting prices for refurbished drives on Amazon, 35~40% cheaper than new. Example here: 16TB Seagate Exos X18 Refurbished at 166€ and New at 260€.
I am considering this option for my home NAS, running with BTRFS RAID10, plus important files are backed-up to a cloud storage, but not my media collection.
In your opinion, how risky is it to use refurbished drives ? Do you have to good or bad experience doing so ?

Hello, I would like to identify this plug & socket in order to get replacement parts ! This comes from my electric cook-top from my apartment's kitchen. Obviously something when wrong... I suspect the plug got nudged loose when the handy-man came to replace the dishwasher, causing one contact to have poor connection, heat overtime and destroy itself. I noticed something was wrong because of the plastic smell when I was using the cook-top for a long time at high power.
The white plug was part of a cable with a Schuko on the other end, I cut it off. The black socket was part of the cook-top. Both were pretty much melted together at this point.
