Posted: Wed Dec 14, 2005 2:17 pm Post subject: fsck on a raid volume |
|
|
I have set up a few mirrored partitions, however I am having some trouble with them.
The problem is a fsck is failing on them, however I can mount them and they seem to work fine -:
Code: | fsck.ext3: Invalid argument while trying to open /dev/md5
The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device> |
I had to comment stuff out in /etc/init.d/checkroot so that it didn't do a fsck to get the system to boot.
Appropriate configs follow -:
/etc/mdadm.conf
Code: | DEVICE /dev/sda*
DEVICE /dev/sdb*
ARRAY /dev/md1 devices=/dev/sda1,/dev/sdb1
ARRAY /dev/md4 devices=/dev/sda4,/dev/sdb4
ARRAY /dev/md5 devices=/dev/sda5,/dev/sdb5 |
/etc/raidtab
Code: | raiddev /dev/md1
raid-level 1
chunk-size 64
persistent-superblock 1
nr-raid-disks 2
device /dev/sda1
raid-disk 0
device /dev/sdb1
raid-disk 1
raiddev /dev/md4
raid-level 1
chunk-size 64
persistent-superblock 1
nr-raid-disks 2
device /dev/sda4
raid-disk 0
device /dev/sdb4
raid-disk 1
raiddev /dev/md5
raid-level 1
chunk-size 64
persistent-superblock 1
nr-raid-disks 2
device /dev/sda5
raid-disk 0
device /dev/sdb5
raid-disk 1 |
Any ideas? |

Could you show us your partitions?
Code: | # fdisk -l /dev/hd{a,b} |
If possible, a list of the commands you ran to get your RAID up and running. I didn't thing raidtab was part of mdadm package... can't say for sure 'cause a long way from my box but you might want to check.
I'd try the following command to populate your /etc/mdadm.conf
Code: |
# mdadm --detail --scan
# mdadm --detail --scan >> /etc/mdadm.conf
|
This is what I did to get it running:
Code: |
# fdisk -l /dev/hda # make disk partitions
Disk /dev/hda: 122.9 GB, 122942324736 bytes
16 heads, 63 sectors/track, 238216 cylinders
Units = cylinders of 1008 * 512 = 516096 bytes
Device Boot Start End Blocks Id System
/dev/hda1 1 195 98248+ fd Linux raid autodetect
/dev/hda2 196 1165 488880 fd Linux raid autodetect
[...]
# mdadm --create --verbose /dev/md0 --level=1 --raid-devices=2 --spare-devices=1 /dev/hd{a,b}1 # make RAID1
# mdadm --create --verbose /dev/md1 --level=1 --raid-devices=2 --spare-devices=1 /dev/hd{a,b}2 # make RAID1
# mdadm --detail /dev/md0 # check raid
# mdadm --detail /dev/md1 # check raid
# mdadm --detail --scan >> /etc/mdadm.conf # populate config file
# mke2fs /dev/md0 # ext2
# mke2fs -j /dev/md1 # ext3
|
Hope this helps

It sounds like there is a typo in your /etc/fstab |

That is why it is good to have more than one set of eyeballs. (hint) |

My raid partition wasn't getting recognised as a ext3 partition by fsck, how is this sparc specific? |

because the installation is slightly different, therre are labels and slices that others wouldn't understand and on top of it all, you are installing on a sparc.
Sparc problems go in here whether they can be translated to other architectures or not.
