Posted: Mon Oct 01, 2012 5:10 pm Post subject: [SOLVED] filesystem check error borks boot |
|
|
I went to boot Gentoo this morning and was met with a series of errors that result in an unset hostname and a read-only filesystem. I had to reboot a few times to capture a picture with scroll lock:

There are a few more errors that appear but I can't capture (or read) them in time before agetty or whatever loads. What's strange to me is dosfsck is trying to run when I don't have any auto-mounted NTFS or FAT partitions. sda1 is /boot, ext2; sda2 is /, ext4; sda3 is /home, ext4; I believe this may have been caused by installing dosfstools (which I needed to do in order to format an SD card last night before bed). I haven't touched anything relating to the system in a few days, and it booted just fine last night...
Any ideas? I tried to load the rescue boot option and it didn't even get to a bash prompt...
PROBLEM: my `/etc/fstab` file had 2s in the last field for my not-necessary-at-boot filesystems.
SOLUTION: By changing the fields to zero (0), I told fsck not to check them at boot and avoided the problem. Thanks to BillWho for the /etc/fstab fix.

when in the ro sort of booted state
Code: | mount -o remount,rw /
emerge --unmerge dosfstools | if that doesn't work boot a cd, fsck any and all partitions, mount the gentoo partitions, enter the chroot, Code: | emerge --unmerge dosfstools |

sporkbox
fsck checks for a file /fastboot and if it exists it will skip filesystem checking.
Not sure about dosfsck, but it might be worth a shot. You might have to boot a live media to create the file or try remounting rw
As far as I know, fsck looks at fstab to determine filesystems to check. _________________ Good luck

I had seen something about /fastboot on some other threads I saw. I'll give that a shot. I also thought that I might've left something in fstab to automatically mount, but it doesn't look like it:
Code: |
# /etc/fstab: static file system information.
#
# noatime turns off atimes for increased performance (atimes normally aren't
# needed); notail increases performance of ReiserFS (at the expense of storage
# efficiency). It's safe to drop the noatime options if you want and to
# switch between notail / tail freely.
#
# The root filesystem should have a pass number of either 0 or 1.
# All other filesystems should have a pass number of 0 or greater than 1.
#
# See the manpage fstab(5) for more information.
#
# <fs> <mountpoint> <type> <opts> <dump/pass>
# NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.
/dev/sda1 /boot ext2 noatime 1 2
/dev/sda2 / ext4 noatime 0 1
/dev/sda3 /home ext4 noatime 0 2
/dev/cdrom /media/dvd auto noauto,ro,user 0 0
/dev/sdb1 /mnt/win7 ntfs-3g noatime,noauto,user,rw,umask=0007,gid=100 0 2
/dev/disk/by-label/D2 /media/d2 vfat noatime,noauto,rw,user,umask=0007,gid=100 0 2
/dev/sd /media/sd auto noatime,noauto,rw,user 0 2

(Note: I'm accessing Gentoo's hard drive from Win7 with ext2fsd. It mostly works...)
DONAHUE: I'll go try that now. It's not worth having those tools installed if they're gonna cause problems.
EDIT (Now on Gentoo): Is it normal for the /fastboot file to disappear after booting? It's no longer there. At any rate, I was able to unmerge dosfstools. I'll reboot and see if it fixed the problem.

Yes, fastboot and /forcefsck ( which forces a check) will be removed... _________________ Good luck

Could you tell me what the difference is between 2 and 0 in the last field? Does changing them to zero simply disable them from automatic fsck'ing? |

fsck will assume that the filesystem does not need to be checked if set to 0. You should man fstab for more info _________________ Good luck

Alright, thanks. The fstab edit fixed it and allowed `dosfstools` to remain on my system.
I'll have to remember that remount trick though! Thanks a lot for the help, guys. I'll mark the topic solved. |
