Sorry for my earlier message...

Well, I've outdone myself again. I think that last message went to the list, since I'd forgotten about all the config options that listservers can have. Again, sorry for that being totally out of place. Now, if you're not all furious at me, I need some help getting software (R)AID working on my

Re: resizing raid partitions

Hmm, well i took your advice and it has seemed to work. I havent done a thourough check for corruption, but there doesnt seem to be any major problems. I had a linear raid partition over 4 drives (1 raid partition on each drive). I used ext2resize to resize the partition to below the last disk, t

Surge + Martin, many thanks for your fast response. Sorry, the cause of the fault is obviously NOT the (latest?) version of the raid tools. I just downloaded raidtools-19990824-0.90.tar.gz which seems to be the latest one on ftp.de.kernel.org and comiled it on my machine. Same result as before.

Hi, thanks for your help I ordered to make a try a P III 450/384RAM/SCSI 2940U2W with 2x Ultrastar ES9 in raid-1 running on redhat6.1 hope to get it in 4 days and make the practice :) > You should take measures that you WILL notice the first disk failure by > monitoring /proc/mdstat - or you wil

reconstruction has failed -- sort-of

I have a production system with raid5 0.42 tool set. Disk A of a 3 disk set failed a couple of days ago on a power cycle. The array was downed successfully PRIOR to the failure, the drive simply did not spin up and appears totally dead. I've replaced the drive and done a ckraid /etc/raid5.conf

Lilo for second disk?

Hi, this is only vaguely connected to Raid, but here goes anyways. I have a machine with two identical disks set up as RAID 1, including the root partition, but not the /boot where vmlinux resides. /boot is mirrored with a script when it changes. I can unplug the second disk and the machine comes

Need help with RAID1

I try to set up a RAID 1 mirror made up of 2 SCSI drives 4MB each. The drives are connected to te system via an AIC78xx controller that works just fine with single disks. Each disk has one singe partition that covers the whole disk. According to the Software-RAID HOWTO, i changed the patition ty
