[Bug 1447879] Re: fscking btrfs consisting of multiple partitions fails

 

I will ask on the mailing list.  It is failing to mount /home.  The
lines in /etc/fstab for root and /home are identical, except that one is
subvol=@ and one is subvol=@home.

Root mounts just fine.  When it comes time to mount /home, systemd is
trying to check the filesystem but that isn't going succeed as all the
parts are already mounted for root.

There are some logs included in earlier responses.  No clues as to the
actual problem though.  I will reboot and get the logs for your request.

Title:
  fscking btrfs consisting of multiple partitions fails

Status in systemd package in Ubuntu:
  New

Bug description:
  I have two SSDs in raid0 (striped) configuration with my root and home
  as separate subvolumes.  This setup has worked fine for several Ubuntu
  releases, but fails with systemd on 15.04.  systemd does manage to
  mount root, but then looks like it is trying to fsck the "disk" for
  home which is nonsensical.  After 90 seconds it drops into a useless
  shell where I can't fix things.

  Relevant lines from /etc/fstab

  UUID=3ff68715-0daa-4e44-8de2-0997f36d8ab6 /               btrfs   defaults,device=/dev/disk/by-id/ata-Crucial_CT960M500SSD1_1347095B97B4-part1,device=/dev/disk/by-id/ata-Crucial_CT960M500SSD1_1338094EA3CA-part1,autodefrag,compress=lzo,subvol=@ 0       1
  UUID=3ff68715-0daa-4e44-8de2-0997f36d8ab6 /home           btrfs   defaults,device=/dev/disk/by-id/ata-Crucial_CT960M500SSD1_1347095B97B4-part1,device=/dev/disk/by-id/ata-Crucial_CT960M500SSD1_1338094EA3CA-part1,autodefrag,compress=lzo,subvol=@home 0       2

  
  Note how the lines are identical except for the subvol value.  I originally didn't have the device= bits either but had to add it for root because of how `btrfs device scan` is run.  With or without it present doesn't make any difference for home.

  There is no such problem booting with upstart
