Hi When your linux boots up with ataraid, it automatically uses /dev/ataraid/d0pN for all the usual stuff like fsck, clearing stale file i-nodes, etc. If you want to check manually or fix something because there are bad blocks on one of the participating disks, you may want to play safe, i.e., boot your computer without ataraid from another device not participating in raid and fix the problem. If another device is not available, boot up with a rescue floppy/cd without raid (you can pass append line to see the ide disks seperately but not load kernel with ataraid support) If you know which partition has problems, it gets simpler sometimes. You dont have to reboot as explained above. Just unmount the problem partition if possible (if thats not a critical partition like /usr or /usr/local etc) and fix hdeN and hdhN only for that partition. There is probably some smart way out there that I dont know, read HOWTO docu for md raid Murty Rompalli On Tue, 10 Dec 2002, Pavlos Parissis wrote: > Hello, > When we have ataraid enabled from the kernel and we use /dev/ataraid/d0pN > for RAID 1 and kernel see also the 2 disks as dev/hde and /dev/hdh, in > which device > i have to check for badblocks. > > PAvlos > > >
