 Posted: Tue Dec 13, 2011 12:42 pm Post subject: [SOLVED] Weird mount problem |
 |
|
Yesterday I've noticed strange behaviour...after boot I was unable to log into the KDE 'cause it was unable to find my home directory. I had to mount it manually and I have to everytime after boot.
What is strange that mount -av has this output:
| Code: |
mount: /dev/sda2 already mounted on /home
mount: /dev/sda4 already mounted on /mnt/disk
mount: shm already mounted on /dev/shm
nothing was mounted
|
however its not mounted...how I said, I have to do it manually
Another strange thing from my dmesg:
| Code: |
Dec 13 13:03:51 lukyn kernel: [ 5.261328] EXT4-fs (sda1): couldn't mount as ext3 due to feature incompatibilities
Dec 13 13:03:51 lukyn kernel: [ 5.272246] EXT4-fs (sda1): couldn't mount as ext2 due to feature incompatibilities
Dec 13 13:03:51 lukyn kernel: [ 5.299760] EXT4-fs (sda1): mounted filesystem with ordered data mode. Opts: (null)
|
About other partition there's no mention until I mount it manually. I have no idea why it tries mount as ext3, ext2 first, when my fstab is this.
| Code: |
/dev/sda1 / ext4 noatime 0 1
/dev/sda3 none swap sw 0 0
/dev/sda2 /home ext4 auto,noatime 0 1
/dev/sda4 /mnt/disk ext4 auto,noatime 0 1
shm /dev/shm tmpfs nodev,nosuid,noexec 0 0
|
I didn't change anything for long time. There was some udev updates, so I tried to downgrade it back to older version, but no help here. At this moment I have no idea whats going on and any help is appreciated

| I have the same problem but with /dev/pts. I solved the problem adding to a high runlevel the init script which was written by me. That script does mounting a needed filesystem. |

Try taking out the 'auto' flag. I don't use that on my mounts. Maybe that's contributing to the problem.
Also, are the last parameters line-wrapped in your example or are they really separate lines in the config file? They shouldn't be on separate lines. |

auto is not problem at all, lines are ok
I tried older backup and I updated it and there is no problem, so I have something broken and I have no idea how to find whats going on |

Hi LukynZ,
| Code: |
Dec 13 13:03:51 lukyn kernel: [ 5.261328] EXT4-fs (sda1): couldn't mount as ext3 due to feature incompatibilities
Dec 13 13:03:51 lukyn kernel: [ 5.272246] EXT4-fs (sda1): couldn't mount as ext2 due to feature incompatibilities
Dec 13 13:03:51 lukyn kernel: [ 5.299760] EXT4-fs (sda1): mounted filesystem with ordered data mode. Opts: (null) |
This is normal.
Your kernel doesn' have ext2 or ext3 fs support,I get it too.
I agree with gentoo_ram: take out the auto flag.
Gerard.

Maybe mounts overlap? I mean, there are 2 mounts in a single directory... check it out with

No, it does not.
Can you post your fstab? also, in the startup prevent KDM from starting and see if the issue persists.

Disabling KDM from startup doesn't solve problem
fstab
| Code: | /dev/sda1 / ext4 noatime 0 1
/dev/sda3 none swap sw 0 0
/dev/sda2 /home ext4 noatime 0 2
/dev/sda4 /mnt/disk ext4 noatime 0 2
shm /dev/shm tmpfs nodev,nosuid,noexec 0 0

You've enabled kernel automouting?
Also see if some relevant configs remain from etc-update (especially in /etc/init.d).

please disable automounting. It is not needed at all.

Copy /proc/mounts to /etc/mtab and reboot

| Wake up pretty old thread, but i had same problem and adding "rootfstype=ext4" to boot options did the trick. |

Adding "rootfstype=ext4 rw" to bootargs really helped but wasn't quite enough. I was then presented with:
| Code: | | [ 1.191124] EXT4-fs (mmcblk0p2): Filesystem with huge files cannot be mounted RDWR without CONFIG_LBDAF |
After a quick google search I found this page (https://kuttler.eu/en/post/filesystem-with-huge-files-cannot-be-mounted-read-write-without-config_lbdaf/?c=300806).
Turns out that the mkfs.ext4 utility (which I originally used to format the partition to EXT4) has "huge_file" support enabled by default. I fixed this by running the following command as suggested in the previous link:
| Code: | | tune2fs -O ^huge_file /dev/sdc2 |
Everything is working now!
P.S. Alternatively I could have enabled CONFIG_LBDAF in my kernel config and rebuilt. But I don't plan on having 2TB files on this system so using tune2fs was easier for me. |
