removing a raid disk

Hi, is there a way to remove a RAID-1, or to convert the array to an standard ext2fs, without erasing all the files on the disk ? I would like to keep all the files without having to do an entire restore of a previous backup which takes a very long time. Thanks. --- Sylvain BARTHELEMY,

Hi, I just wanted to warn everybody not to use raid0145-19990824-2.2.11 together with kernel 2.2.14: at least in my configuration (two IDE drives with RAID-1, root on /dev/mdx) the kernel panics with "B_FREE inserted into queues" at boot time. This seems to be some kind of a known problem,

I think Andrea Arcangeli has a fix for this. Search the lkml archives for something on set blocksize. It's an incremental patch over RAID 0.90. Brian Hi, I just wanted to warn everybody not to use raid0145-19990824-2.2.11 together with kernel 2.2.14: at least in my configuration

I had the same problem with the 2.2.14pre18 configuration I'm using. I can tell you how to get around it, but not why it happens. (Hey, I'm a newbie!) If you edit the /etc/fstab and tell the system not to dump or e2fsck the raid (set the 5th and 6th columns to 0), everything will boot and

Hello everyone, We have had a 108G RAID 5 array (8 * IBM 16G) running rock solid for months on Linux 2.2.11 using raidtools 0.90.0. We had the array filled to about 29G when hardware started to hose out. /dev/hdc started to get weird, and we took it out, replacing it with another
