Hi,
I have a 4 disk RAID 5 array. I upgraded to the 2.4.20 kernel and one of
my disks went kaput (loose power connector). I fixed the disk and tried to
rebuilt the raid but it locked up hard (no magic sys-req key, no oops,
nothing!). So I rebooted and it locked up everytime it started the recovery
process. So then I tried kernel 2.4.19-rc3 (my old faithful kernel) and it
rebuilt just fine.
More details:
The 4 disks are connected to 2 promise chips. One is on a PCI card and is
just a ATA-100 host adapter. The other is on the motherboard and is a raid
adapter that I run in straight ATA host adapter mode. All the disks are
masters. Here are the lines from lspci:
00:0f.0 RAID bus controller: Promise Technology, Inc. PDC20276 IDE (rev 01)
00:09.0 Unknown mass storage controller: Promise Technology, Inc. 20267
(rev 02)
Before it locked up the second time it did a ext-3 journal recovery on
the disk and that worked ok. I mention this because that shows the
read/write path to the drives is at least partially working.
Since it locks up completely, I'm not sure how to debug any further. Does
anyone know what the problem might be?
Thanks,
David
