Linux RAID and mdadm

Belisarius · 11-23-2004, 01:04 PM

I've got two drives I'm trying to mirror. I setup the mirror just fine, having first changed the partitions on each to "fd", or the Linux RAID filesystem. They were RAIDed and I was able to mount the newly created device, /dev/md0. But for some odd reason I wasn't able to write to it. I tried to set the readwrite property on the array from mdadm, but it kept telling me the device was busy. I've unmounted, rebooted, and taken the drive down, nothing. Anyone give me some pointers as to what to do?

Well, I'm glad I decided to do this with Slackware, as I'm learning how to do all the nitty-gritty stuff I had taken for granted under Redhat.

I never ran mke2fs on the newly created RAID device, I only partitioned it. So I never had a filesystem to write to. It all works now.
