 |
|
After booting Linux 2.4.21 for the first time my root partition (reiserfs) could not be mounted read-write. /etc/init.d/checkroot failed when executing | Code: | | mount / -n -o remount,rw &>/dev/null |
and complained | Code: | | Root filesystem could not be mounted R/W :( |
My root partition entry in /etc/fstab was | Code: | | /dev/hda8 / reiserfs errors=remount-ro 0 1 |
After I changed it to | Code: | | /dev/hda8 / reiserfs defaults 0 1 |
checkroot succeeded.
Anybody having the same problem? With Linux 2.4.20 I didn't have this problem, although I had the remount-ro error option in fstab.
Greetings, Jukka |

The option parsing code for reiserfs, found in fs/reiserfs/super.c, changed between 2.4.20 and 2.4.21. I belive the new code fails if it encounters mount options in does not understand at all, and reiserfs has never had any vaild errors= option. |

yeah, i had the same problem. my first quick-and-dirty-solution was hardcoding /dev/hda2 into the mount-command of the script (it worked then, god knows why), but your solution looks much better  |

What is the 0 1 mean at the end of the line? Mine was set to 0 0 before.
Edit: Nevermind ... man fstab had the answer:
| Code: |
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.
