Hi, I've been stumbling the last couple of weeks, getting a new box working. The problem is that I have a Promise FastTrack SX4 with 512MB cache and four 300GB Maxtor SATA drives connected to it. I've used mdadm to create a RAID5 array, which is about 879G.
On this array, I've tried LVM (with ReiserFS, XFS, JFS, Ext2, Ext3 on top of it) as well as creating the same kind of file systems without LVM. I use rsync to copy a bunch of files (several GB's) to the designated filesystems. But after a while, all file systems get corrupted and 'dmesg' lists all kinds of memory corruptions in 'dm' and so on. Hence, the file copying stops. Kernels, I've tried, are: - 2.6.9-r1 - 2.6.11-r4 - 2.6.11-r5 - 2.6.11.7 - 2.6.12-rc2 ... but the problem persists. When I run 'top' in a separate window, I see the amount of physical memory dropping and dropping from about 838MB free, down to about 8M free. Then is when the problems arise. So, I now tried several times to stop the file copying before it gets too low. Then the amount of free physical memory remains constant (instead of being freed). Only when I umount the filesystem and remount it, the amount of free memory is back to the 838MB and I can copy another bunch of files (without any corruption). Is this pointing to a memory leak problem in md, or is it a problem with RAID5 on md?
