[Bug 750209] Re: btrfs does a full partition check on each boot

[Alex Sorokine]

Got this problem after upgrading to Natty and installing all recent
updates: fsck is run on every boot, fscking 1TB btrfs volume takes 52
min.  As a temporary solution I have disabled btrfs partition in fstab
and I mount it manually.  Partitions I am using:

/dev/sdb1 on / type ext4 (rw,errors=remount-ro,commit=0)
/dev/sda1 on /mnt/disk1 type btrfs (rw)

btrfsck results attached.

Title:
  btrfs does a full partition check on each boot

Status in Release Notes for Ubuntu:
  New
Status in “btrfs-tools” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: btrfs-tools

  Since bug #660649 has been closed btrfsck does a full filesystem check
  during each boot. This can cause massive delays during boot time
  depending on the size of the partition.

  Running btrfsck during startup isn't very usefull at the moment:
    - btrfsck does a full check even if the filesystem has been unmounted correctly.
    - btrfsck doesn't repair anything it just checks for errors.
