Another 24 error-free hours on the server with the test kernel running the MySQL/Icinga2 combination and creating btrfs snapshots every 5 minutes.
I'd like to add that this server, which previously experienced frequent false ENOSPC conditions with the Xenial release kernel, used a fairly plain btrfs configuration at all times: - The '-o nodatacow' mount option was *not* used (in contrast to the test script). - Disabling copy-on-write (CoW) on a per-file basis (using chattr +C) was *not* used. # mount | grep /volumes/01 /dev/sda2 on /volumes/01 type btrfs (rw,noatime,nodiratime,ssd,space_cache,subvolid=5,subvol=/) # lsattr /var/lib/mysql/ibdata1 ---------------- /var/lib/mysql/ibdata1 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1584052 Title: btrfs: file write crashes with false ENOSPC during snapshot creation since kernel 4.4 - fix available To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1584052/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
