Re: Software Raid issue

I had the raidtools installed on the CD, but am trying to download the linked software and install this one.

I know there is no lsraid as I run slocate -u every day, and locate lsraid produced nadda ;)

Running raidstart is done at boot, note I have 2 separate Raid stripes, and both are mounted and working and active.

The active and working is verified by using "cat /proc/mdstat"

[root@masterc root]# cat /proc/mdstat
Personalities : [raid0]
read_ahead 1024 sectors
md1 : active raid0 sdb[1] sda[0]
143374592 blocks 64k chunks

md0 : active raid0 sdd[1] sdc[0]
71687168 blocks 64k chunks

unused devices:

Re: Software Raid issue

Installed the raidtools package, and kind of like cat /proc/mdstat here are the results.

[root@masterc tmp]# lsraid -A -g -a /dev/md1
[dev 9, 1] /dev/md1 E475ADD5.0CB7B814.11161BB8.D84F5860 online
[dev 8, 0] /dev/sda E475ADD5.0CB7B814.11161BB8.D84F5860 good
[dev 8, 16] /dev/sdb E475ADD5.0CB7B814.11161BB8.D84F5860 good

Re: Software Raid issue

Okay, I'm stumped.

Perhaps remove and rebuild the filesystem, using the newly installed raid tools. If its empty, when its rebuilt, it should be fine.

I hate messing with Linux disk layout after its running, I'm an LVM man.

If I think of anything actually useful, I'll post.

Re: Software Raid issue

Yeah, Im stumped too. All looks okay, and I had no problems until I made those tar files. I was trying to avoid rebuilding the file system as this raid device has some production data on it.

fsck reveals no errors, so it's very strange.

I'll let you know if I resolve it ;/

Re: Software Raid issue

Looks like it was the raidtools I was using that caused the problem. After updating, I unmounted and fsck'd. The fsck found a ton of errors and fixed everything up. Since the raidtools didnt mess with fsck, must be something else in the package.


Thanks for the nfo, and at least I dont have to rebuild the fs ;)
