AFAIK Ingo is hard working at getting RAID ready for 2.3
It needs some porting to the new unified buffer-cache architecture
and there is the 12+ disks issue too (which causes superblock restructuring).
It would, however, be really nice to have an ETA on it, so we can
plan to back up important stuff and get ready for some 2.3+RAID testing
in time:)(Ingo, are you reading this? ;)

raid problem
Hi I'm using a redhat 6.1 with a 2.3.21 kernel. the raid/raid5 support is compiled in the kernel (aka not module). I have 5 hard drives (IBM-DJNA-351520, 14664MB w/430kB Cache, CHS=29795/16/63, (U)DMA) who are called hdb to hdf. All of these disks only have one partition on them which is hd?1 and which takes all the room. Here is my /etc/raidtab : raiddev /dev/md0 raid-level 5 nr-raid-disks 5 nr-spare-disks 0 persistent-superblock 1 parity-algorithmleft-symmetric chunk-size 32 device /dev/hdb1 raid-disk 0 device /dev/hdc1 raid-disk 1 device /dev/hdd1 raid-disk 2 device /dev/hde1 raid-disk 3 device /dev/hdf1 raid-disk 4 which is, conforming to the howto, right. and when i try : # mkraid /dev/md0 here is what i have : handling MD device /dev/md0 analyzing super-block disk 0: /dev/hdb1, 15016648kB, raid superblock at 15016576kB disk 1: /dev/hdc1, 15016648kB, raid superblock at 15016576kB disk 2: /dev/hdd1, 15016648kB, raid superblock at 15016576kB disk 3: /dev/hde1, 15016648kB, raid superblock at 15016576kB disk 4: /dev/hdf1, 15016648kB, raid superblock at 15016576kB mkraid: aborted, see the syslog and /proc/mdstat for potential clues. and, well, nothing appears in the syslog, and /proc/mdstat remains unchanged. anyone have a clue ? -- Cordialement Mathieu Arnold PGP key id : 0x2D92519F IRC : _mat ICQ 1827742 http://www.mat.cc/
strange RAID problem - RAID doesn't work at boot
Ok, I am setting up a RAID box, a PII-350 with an ASUS P2B-S mobo (adaptec 7000 chip). I found some document on the web that explained how to set up software RAID correctly (I think it was a HOWTO, but it seems to have gone missing, I cant find it anywhere). I got it working with kernel 2.2.5 (I'm using RAID-0). I have two RAID devices, md0 and md1. /home is on md0 and /usr is on md1. However, I was having a problem. When I wrote stuff to the disk and then compared it to the source (a cd) they differed slightly. That state of affairs not being acceptable I decided to try a newer kernel (upon the suggestion that the older scsi drivers might be faulty). So I downloaded 2.2.10 and compiled and installed it as I thought was correct (I compiled in md support and RAID-0 mode as well as generic scsi support - for my HP CD-writer and the AIC-7000 support for my scsi card). Now the machine will not boot at all if I have /dev/md0 or /dev/md1 anywhere in my fstab. It fails when checking the filesystems on md0 and md1, saying "short read opening /dev/md0" (same for md1). I am having a really hard time understanding what is going wrong here. I would be most grateful for any suggestions that people might have (this machine is due very shortly, I need to get it finished so I can deploy it) and also, if anyone knows a good document that explains how to do software RAID, step by step, I would be grateful for that. Thank you, Sean Harper
Re: strange RAID problem - RAID doesn't work at boot
Yes, and when I boot with the original 2.2.5 kernel that I made it works fine. Also, when I boot with the new kernel and do not include md0 or md1 in the fstab and then manually mount them it works just fine.
