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 ?
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.

Reminiscent of the renowned pastry from Bordeaux (France) le Canelé Bordelais, the main design element of this lamp is known to french mechanics engineers as cannelure.
I designed this lamp with the goal to utilize the spiral-vase 3D printing mode to create a beautiful object, with a minimalist, retro, industrial style.

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 !
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
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.
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:
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):
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.
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).
m4nas:~:% lsblk

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:
replace, then swap the disks in the drive-bayMethod #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 !).
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
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:
m4nas:~:% btrfs filesystem show

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:
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

In the end, the swap from USB to SATA worked perfectly !

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).
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.
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:
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
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 !
I hope this post can be useful to someone in the future, or at least was interesting to some of you !
Anime wife. I think.
