 Posted: Sun Mar 20, 2005 6:22 am Post subject: problems when mounting JFS partition |
 |
|
Each time I boot gentoo I can't mount one of my JFS partitions
| Quote: |
# mount /dev/hda8 /mnt/tmp/
mount: wrong fs type, bad option, bad superblock on /dev/hda8,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
|
then I do fsck.jfs /dev/hda8 and it mounts clean
but I need to do it each boot
what's the strange behaviour? |

Can you post your fstab file, as well as the output from dmesg | tail ?
Also, do you have jfsutils installed? |

I've the same problem (I think so).
The message appears while booting. When I'm trying to mount it manually after boot it also gives that message. I've to manually fsck the partition and then mount it - then it works.
I think, fstab doesn't affect this problem. Jfsutils is of course [fsck.jfs works] installed.
It is on kernel 2.4.28-gentoo-r9 and 2.6.16-gentoo-r7 |

After a bit of googling I found this jfs mount option:
errors=continue
which I have added to my fstab:
/dev/sda2 /mnt/mythtv jfs errors=continue 0 0
If this works then I will notify here. |

| no errors=continue does not help...I am probably going to reformat & use reiser instead. |

| Is it really impossible to solve that ? Doesn't anybody have the problem too ? |

once had same problem, reformated using reiserfs, because jfs is too buggy to use it...
should you loose power, you'll end up with corrupted fs

| Well, I haven't experienced the bugs of jfs, I've never lost my data from jfs partition, and jfs is very fast with many small files... I felt a huge difference (in speed) when changed fs from reiserfs. |

it seems that you're the lucky one  | emdej wrote: | | and jfs is very fast with many small files... I felt a huge difference (in speed) when changed fs from reiserfs. |
again it is very strange because reiserfs is the best when dealing with small files... maybe you didn't add notail option to your fstab when using reiserfs 
I used jfs on my old lapy (Pentium 233 MMX), because all the people said it does not utilize so much CPU power as reiserfs, but I didn't like to check my root partition every few mounts because it complained about being corrupted...
I'll never use JFS again, there's no sense...
if you want speed - go for reiserfs (or even reiser4, but not tried that)
if you want real stability - go for ext3 (as it is the most stable fs)
if you do not care about journalling (stability) and want speed - go for ext2...
JFS IS BUGGY

I use JFS on my mythtv box & is very fast at deleting big files....maybe 5-10* faster than ext3....since I often record & delete huge mpeg files with mythtv it seems like the pefect file system.
I have had no problem with corruption...just this irritating thing with the file system not mounting after a crash. Perhaps kernel 2.6.17 will work better ? |

The sixth and last field in the /etc/fstab file, tells the fschk program which paritions to check on bootup. If it is zero, the partition never gets checked. If a JFS partition was not cleanly umounted you can not mount it till a check has been run on it (I think that's also the case with most other filesystems). So you have to do that manually or let fschk do that for you on bootup. But fschk only does this for you of the sixth field is '1' or '2'.
man fstab:
| Quote: |
<...>
The sixth field, (fs_passno), is used by the fsck( program to determine 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.

my /etc/fstab:
| Code: |
<...>
/dev/sda6 / jfs noatime 0 1
/dev/sda8 /mnt/data vfat defaults,rw,uid=christoph,gid=users 0 0
# LVM2 volumes
/dev/vg/usr /usr jfs noatime 0 2
/dev/vg/home /home jfs noatime 0 2
/dev/vg/opt /opt jfs noatime 0 2
/dev/vg/var /var jfs noatime 0 2
/dev/vg/tmp /tmp jfs noatime 0 2
/dev/vg/scripts /scripts jfs noatime 0 2
