@sun@Lars I decided against using btrfs for another couple years this past week after reading plenty of recent reports of its failure to recover from errors, along with its longstanding reputation of being unable to recover from many types of errors, see also https://www.usenix.org/system/files/atc19-jaffer.pdf
#btrfs would be a lot better if it *handled* errors rather than detecting them (which it's great at) and then blowing the fuck up.

anybody know if #btrfs has improved this situation with regard to filesystem recoverability after medium errors common on consumer SSDs?

So after multiple power losses yesterday; and multiple instances of btrfs log tree corruption yesterday. AND swapping out kernels and simulating power failures this morning. I've got a lot of anecdotal evidence that Liquorix Kernel 6.15.5 has something odd going on with how either the timing of it writing it's log tree on my NVME, or it's failing to flush the write of the log tree on my NVME.
Lets just say, im going back to openSUSE's vanilla kernel for the rest of my openSUSE adventure. #linux #btrfs#openSUSE #Liquorix

Des personnes par ici ont de l'expérience avec l'utilisation combinée de #bcache et #btrfs ?
Vous auriez des retours d'expérience et conseils / recommandations ?
C'est pertinent comme cache en lecture (surtout) si on a une asymétrie du style 500Go de SSD pour >10To de HDD ?
Il me semble que pour mon cas d'usage c'est la lecture aléatoire qui est la plus pénalisante.

In snac on an ancient Raspberry Pi news, I switched from XFS to Btrfs and my memory pressure issues are now a thing of the past. As a bonus I can use snapshots for backups instead of taring up the many small files that snac generates (it has no traditional database).
I tried tuning various parameters but after some reading came to the conclusion that lots of small files with very little RAM is about the worst case scenario for XFS.
