Hello, I created a raid linear this weekend merging two IDE disks (45g , 10g) on a 2.2.16 kernel with the corresponding patches from http://people.redhat.com/mingo/raid-patches/. Today I moved the raid to another computer (home to work). I compiled a similar kernel and applied the same patches... unfortunately the disk partitions are not recognized on this new system. My kernel boot messages print "unknown partition table". Here is the raid excerpt from the boot kernel messages: md driver 0.90.0 MAX_MD_DEVS=256, MAX_REAL=12 linear personality registered md.c: sizeof(mdp_super_t) = 4096 Partition check: hda: hda1 hda2 hda3 hdb: unknown partition table hdc: unknown partition table autodetecting RAID arrays autorun ... ... autorun DONE. I have searched the web and several mailing lists and found no other similar problems. The next step I was going to take was to try a disk partition repair tool talked about in the Filesystems HOWTO. Other than that, try to rebuild/transfer the raid again tonight. Any suggestions? thanks, donfede
