Well I reverted the change to get a bootable system but something went wrong on the next yum update. It locked in the middle of a package install and had a kernel panic. I was eventually able to get yum-complete-transaction to run without trying to erase every package on the machine but it looks like I got some BTRFS corruption. I think I'm going to wipe it and put the latest F16 (RC/TC/whatever) on it. I'll report back if I'm still having issues.

Take a look at this: http://pipebreaker.pl/dump/2011-10_bootchart.png It's my test machine with btrfs / on old disk (20GB IDE Maxtor). tmpfiles take 30s to run, without any special configuration. Oh, and its F15 system.

I couldn't find systemd-tmpfiles.service... I assume that systemd-tmpfiles-setup.service was the correct file?

Remounting with "-o space_cache,inode_cache" will enable them. Then wait few minutes for caches to be built (I/O will stop when they're ready). Subsequent mounts should be faster. -- Tomasz Torcz ,,If you try to upissue this patchset I shall be seeking xmpp: zdzich...@chrome.pl an IP-routable hand grenade.'' -- Andrew Morton (LKML) -- devel mailing list devel@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/devel

The fsck tool does nothing and will not be the cause of your delay. If your fs gets even one bit corrupted you'll lose everything (just FYI). I've had long mount times on a btrfs drive (no LVM) for a while now. I'm seeing mount take about 7 seconds to complete. I posted this delay to the btrfs list and my message didn't receive a single reply. -- devel mailing list devel@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/devel

I rebooted a few times just to make sure it's not a scheduled fsck (not that there is a full fsck for BTRFS yet) and the hard drive light is on pretty solid the whole time... If I have time this weekend I may try booting live media to do do a manual filesystem setup without LVM and reinstall. It's my laptop so I don't keep anything critical on it.

BTRFS on LVM causes long fedora-storage-init run?
I posted this on the main mailing list but didn't get any hits. Hopefully I'll have better luck here. --- I found the following thread but I don't think mine is the same problem: http://lists.fedoraproject.org/pipermail/test/2011-June/100861.html I am, however, running BTRFS on main main partitions on top of LVM (since anaconda as of F15 still creates an LVM setup regardless of filesystem?) This is the only thing I can think of that's causing the problem. $ systemd-analyze blame | head 47003ms fedora-storage-init.service 30284ms boot.mount 8829ms udev-settle.service 3692ms cups.service 1686ms systemd-vconsole-setup.service 1567ms udev.service 1510ms autofs.service 1403ms fedora-readonly.service 1311ms lvm2-monitor.service 1295ms NetworkManager.service boot.mount I assume just remounts the boot partition as read-write, so I think it's just waiting on fedora-storage-init.service. Any ideas? Thanks, Richard -- devel mailing list devel@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/devel
