Hi All, After several months of operation, i found out that my server is working kinda odd. Here's my /proc/mdstat Personalities : [raid1] md1 : active raid1 sdb5[1] 6297344 blocks [2/1] [_U] md2 : active raid1 sdb6[1] 2104384 blocks [2/1] [_U] md3 : active raid1 sdb7[1] 68573312 blocks [2/1] [_U] md4 : active raid1 sdb8[1] 513984 blocks [2/1] [_U] md0 : active raid1 sda1[0] 104320 blocks [2/1] [U_] unused devices: <none> And this is when I use lsraid on md1 komodo:/var/log # lsraid -a /dev/md1 [dev 9, 1] /dev/md1 FB3ED8EC.9ABBA9C8.624549A1.6C0BDF9F online [dev ?, ?] (unknown) 00000000.00000000.00000000.00000000 missing [dev 8, 21] /dev/sdb5 FB3ED8EC.9ABBA9C8.624549A1.6C0BDF9F good And this is when I use lsraid on md0 [dev 9, 0] /dev/md0 855C73DB.CCF72F98.1C4FFC68.BCA47694 online [dev 8, 1] /dev/sda1 855C73DB.CCF72F98.1C4FFC68.BCA47694 good [dev ?, ?] (unknown) 00000000.00000000.00000000.00000000 missing It seems not all partition is working. In sda, only sda1 is working, and in sdb, sdb5, sdb6, sdb7 and sdb8 is working but not sdb1. I was using software raid thru Yast in first installation. My questions are, why this is happened ? Is RAID1 not working anymore, so if I remove one of the disk it will fail ? How can i resync so all disks is mirrored ? regards, -- Arie Reynaldi Zanahar reymanx at gmail.com http://www.reynaldi.or.id

Well... I guess it's in raidtools packages.. komodo:/var/log # rpm -qf /sbin/lsraid raidtools-1.00.3-231 -- Arie Reynaldi Zanahar reymanx at gmail.com http://www.reynaldi.or.id
raidtools have been deprecated a few years ago in favor of mdadm AFAIK, if you are using a newer kernel with an older array, have you tried looking at it with mdadm? On Fri, 18 Aug 2006, Arie Reynaldi Z wrote:
