Hello everybody, I am installing Linux SuSE 8.0 with kernel version 2.4.18-4GB. This kernel should have already contain the Software-RAID module as advertised by SuSE. I have 3 equal drives. For simplicity I installed complete Linux only in a drive hdb(the boot and the root is in this normal drive) and now I am trying to make a RAID level 0 with the rest 2 drives called hdc and hdd. I have made these two drives into a RAID-drive called /dev/md0 with YaST2 help and it was successfully mounted and used. But each time I rebooted the system, this /dev/md0 could not be recognized at startup and all data in /dev/md0 was lost as well. I needed to mount it again afterwards, that made it a silly idea. What is wrong ? Any hints and helps are gladly welcomed. Here is the message on boot: ... <6>md: md driver 0.90.0 MAX_MD_DEVS=256, MD_SB_DISKS=27 <6>md: Autodetecting RAID arrays. <6> |events: 0000009a] <6> |events: 0000009a] <6>md: autorun ... <6>md: considering hdd1 ... <6>md: adding hdd1 ... <6>md: adding hdc1 ... <6>md: created md0 <6>md: bind<hdc1,1> <6>md: bind<hdd1,2> <6>md: running: <hdd1><hdc1> <6>md: hdd1's event counter: 0000009a <6>md: hdc1's event counter: 0000009a <3>request_module[md-personality-2]: Root fs not mounted <3>md: personality 2 is not loaded! <4>md: do_md_run() returned -22 <6>md: md0 stopped. <6>md: unbind<hdd1,1> <6>md: export_rdev(hdd1) <6>md: unbind<hdc1,0> <6>md: export_rdev(hdc1) <6>md: ... autorun DONE. ...and after some lines below there is other messages: <3>md: invalid raid superblock magic on hdc <4>md: hdc has invalid sb, not importing! <4>md: could not import hdc! <4>md: autostart hdc failed! <6>md: Autodetecting RAID arrays. <6> |events: 0000009a] <6> |events: 0000009a] <6>md: autorun ... <6>md: considering hdd1 ... <6>md: adding hdd1 ... <6>md: adding hdc1 ... <6>md: created md0 <6>md: bind<hdc1,1> <6>md: bind<hdd1,2> <6>md: running: <hdd1><hdc1> <6>md: hdc1's event counter: 0000009a <6>md: hdd1's event counter: 0000009a <6>md: raid0 personality readahead registered as nr 2 <6>md0: max total readahead window set to 496k <6>md0: 2 data-disks, max readahead per data-disk: 248k <4>raid0: looking at hdc1 <4>raid0: comparing hdc1 (80418112) with hdc1(80418112) <4>raid0: END <4>raid0: ==> UNIQUE <4>raid0: 1 zones <4>raid0: looking at hdd1 <4>raid0: comparing hdd1 (80418112) with hdc1(80418112) <4>raid0: EQUAL <4>raid0: FINAL 1 zones <4>raid0: zone 0 <4>raid0: <4>raid0: <4>raid0: <4>raid0: <4>raid0: <4>raid0: <4>raid0: <4>raid0: <4>raid0: FYI here I give the content of some important files: /etc/fstab: /dev/hdb3 / reiserfs defaults 1 2 /dev/hdb2 /boot reiserfs defaults 1 2 /dev/md0 /dataraid auto noauto, user 0 0 devpts /dev/pts devpts defaults 0 0 /dev/cdrecorder /media/cdrecorder auto ro,noauto,user,exec 0 0 /dev/cdrom /media/cdrom auto noauto,user,exec 0 0 /dev/fd0 /media/floppy auto noauto,user,sync 0 0 usbdevs /proc/bus/usb usbdevs noauto 0 0 proc /proc proc defaults 0 0 /dev/hdb1 swap swap pri=42 0 0 /etc/raidtab: raiddev /dev/md0 raid-level 0 nr-raid-disks 2 persistent-superblock 1 chunk-size 32 device /dev/hdc raid-disk 0 device /dev/hdd raid-disk 1 /etc/mtab: (not mdtab, inside there is no md0 entry) /dev/hdb3 / reiserfs rw 0 0 proc /proc proc rw 0 0 devpts /dev/pts devpts rw 0 0 /dev/hdb2 /boot reiserfs rw 0 0 shmfs /dev/shm shm rw 0 0 usbdevfs /proc/bus/usb usbdevs rw 0 0 - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
