/usr/share disappeared
Hi, yesterday something weird happend: While browsing with Firefox (39.0) as a normal user, Firefox suddenly crashed, and after this the directory /usr/share was gone - completely vanished into thin air. Fortunately I had a backup, but the incident scared me a little. Has anybody ever experienced something like this? As all my filesystems are btrfs, I wonder if btrfs can be considered stable enough, or would ext4 be a safer choice? Regards, Bernd

Ouch, that sounds scary. Are you sure firefox caused the crash? Perhaps firefox crashed just because /usr/share suddenly vanished? In general i'd say btrfs is stable enough. It depends on what features you use and what kernel you run. I've personally run btrfs since 2012(?) and have had one dataloss that was due to user error (failed drive, should not have used "btrfs dev delete") Usually when btrfs fucks up, you'll notice it in the kernel log.

Yes, the latter, I think. Still have no clue what happend, couldn't find anything peculiar in the log file. Anyway, the incident strengthend my determination to make backups _really every_ day (sigh...). Bernd

Would be interesting to know what would have happened if you had snapshots. If you had a snapshot and you had a *filesystem* issue, that ought to have been damaged too. -- Fredrik Rinnestam

Aha! It finally pays off placing our man pages in /usr/man instead of /usr/share/man! Seriously though, I think its time to change that. Alan
