I had a slow startup too. I installed Kubuntu 11.10 choosing btrfs as file system, and noticed was booting far slower than ext4. I asked in IRC channel and Chris Mason (wow!) troubleshooted it (how incredible is FOSS world?). [20:33] <cmason> ok, start with the fstab [20:33] <cmason> UUID=d5acc217-d524-4a2d-a937-bad945a047b2 / btrfs defaults,noatime,nodiratime,subvol=@ 0 1 [20:33] <cmason> last number should be a zero, should just change fsck.btrfs to a noop fsck is slow, because it's not intended as a boot-time check
In fact after this change my atom single core boot time dropped from 111 sec to 80 sec Marco -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/791020 Title: Slow boot cause of btrfs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/791020/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
