Hi there,
I've search low and high and havn't been able to find a solution for my problem with a software raid that I have setup under linux.
Kernel: 2.6.6 Controller: PDC202XX (Promise TX2 ATA100 IDE Controller)
Up until recently everything was fine, but recently the array has started playing up and dropping a disk and when I reboot the disk doesn't have the superblock for the md device and as a result can't start, I then explored the disk using cfdisk and the disk had no partition there. So I reformated and this is what I get from mdadm now:
* When I try to assemble the array manually:
cold:~# mdadm -Af /dev/md1 /dev/hd[fjl]1 mdadm: no RAID superblock on /dev/hdj1 mdadm: /dev/hdj1 has no superblock - assembly aborted
* When I assemble the array with the two disks I know work:
cold:~# mdadm -A /dev/md1 /dev/hd[fl]1 mdadm: failed to RUN_ARRAY /dev/md1: Invalid argument
* And mdadm -D
cold:~# mdadm -D /dev/md1
/dev/md1:

2 33 65 2 active sync /dev/hdf1It is usually a raid 5 array with 3 x 120 gig disks on it.
What I'm wanting to know, is despite the fact that hdj1 doesn't have the superblock is there a way I can add it to the array so that I can then start it and hopefuly recover the 200 gig of data on there, which I can then shift off to a hardware array?
