Hi When I was switching to systemd on another debian box I've discovered a problem related with passno field in fstab. I have several md partitions (I am using kernel autoassembly for md, and I am not using initrd). I have systemd v.25-2 (debian experimental).
I have the following entries in fstab for my partitions: UUID=f73bcffa-5b89-4f1d-a296-5f0e6ebf4673 / ext4 errors=remount-ro 0 1 UUID=33a13f77-6e5a-4c1e-b959-d891b0a77488 /home ext4 defaults 0 2 UUID=45e28f49-1822-4b32-b8a4-2a9ac1bf543e /usr/src ext4 defaults 0 2 UUID=8fe78553-ad5e-47f1-8630-bf1fa5d7b608 /var ext4 defaults 0 2 UUID=af8133a0-e9a5-4fcf-81e4-c87c2bb50ac8 none swap sw 0 0 all of this UUIDs are /dev/md devices - and not counting the mirroring disk, all of theese partition is on one physical sata disk. According to manual all is fine here: The sixth field, (fs_passno), is used by the fsck(8) program to deter- mine the order in which filesystem checks are done at reboot time. The root filesystem should be specified with a fs_passno of 1, and other filesystems should have a fs_passno of 2. Filesystems within a drive will be checked sequentially, but filesystems on different drives will be checked at the same time to utilize parallelism available in the hardware. If the sixth field is not present or zero, a value of zero is returned and fsck will assume that the filesystem does not need to be checked. But this cause a problem to systemd when booting: systemd-fsck[1346]: /dev/md0: clean, 86170/458752 files, 954201/1834480 blocks systemd-fsck[3078]: /dev/md2: clean, 312227/1966080 files, 2639961/7864304 blocks (check in 2 mounts) systemd-fsck[3091]: fsck.ext4: Device or resource busy while trying to open /dev/md4 systemd-fsck[3091]: Filesystem mounted or opened exclusively by another program? systemd-fsck[3087]: /dev/md1 has been mounted 23 times without being checked, check forced. systemd-fsck[3087]: /dev/md1: 8010/983040 files (1.2% non-contiguous), 2091221/3932144 blocks Welcome to emergency mode. Use "systemctl default" or ^D to activate default mode. Give root password for maintenance (or type Control-D to continue): I am not 100% sure but if I remind correctly, the "busy one" partition was random within reboots. After conversation with Kay Sievers I've set my fstab entries to this: UUID=f73bcffa-5b89-4f1d-a296-5f0e6ebf4673 / ext4 errors=remount-ro 0 1 UUID=33a13f77-6e5a-4c1e-b959-d891b0a77488 /home ext4 defaults 0 2 UUID=45e28f49-1822-4b32-b8a4-2a9ac1bf543e /usr/src ext4 defaults 0 3 UUID=8fe78553-ad5e-47f1-8630-bf1fa5d7b608 /var ext4 defaults 0 4 UUID=af8133a0-e9a5-4fcf-81e4-c87c2bb50ac8 none swap sw 0 0 I changed the passno fields to 1,2,3,4,0 from 1,2,2,2,0 and this fixes the problem and my system is now bootable: systemd-fsck[1334]: /dev/md0: clean, 86178/458752 files, 954201/1834480 blocks systemd-fsck[3025]: /dev/md4: clean, 2675040/57581568 files, 199580895/230296816 blocks systemd-fsck[3109]: /dev/md2 has been mounted 28 times without being checked, check forced. systemd-fsck[3109]: /dev/md2: 312227/1966080 files (0.4% non-contiguous), 2639961/7864304 blocks systemd-fsck[3190]: /dev/md1: clean, 8033/983040 files, 2067703/3932144 blocks Setting console screen modes. Skipping font and keymap setup (handled by console-setup). ... and login prompt after a while So the problem is somewhere with passno interpretation (according to manual it should work, but it doesn't). regards, -- Mariusz Białończyk jabber/e-mail: ma...@skyboo.net http://manio.skyboo.net _______________________________________________ systemd-devel mailing list systemd-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/systemd-devel
