Hi,

Short history: configured raid5 + lvm2 for data disks. Everything worked fine. When converting root (system disk) to raid 1, I've lost my system disks. I did a reinstall (1st time in 4 years) of Debian and compiled a new kernel 2.6.6.

Now trying to recover my raid 5 + lvm. When raid 5 was up (in degraded mode), I could see all my lv's, so I think all data is still ok.

I had problems with DMA timeout and with the patch mentioned in http://kerneltrap.org/node/view/3040 for pDC20268, which had the same erors in messages.
I've checked the raid with lsraid and two disks seemed ok, although, one was mentioned as spare.
I did a mkraid --really-force /dev/md0 to remake the raid, but after this, I cannot start it anymore.

junk **raid and use mdadm.

anyway you don't tell us which fstab you used for doing the mkraid, and
how it related to the current status of your drives.
