I dont't know why the md1 still can be find and how to delete it. > md2 : active raid5 hda12[2] hda11[1] hda10[0] > 1638400 blocks level 5, 32k chunk, algorithm 0 [3/3] [UUU] > > md4 : active raid5 hdc7[2] hdc6[1] hdc5[0] > 1023872 blocks level 5, 32k chunk, algorithm 0 [3/3] [UUU] raid 5 on the same disk (cool!) i just want to test whether a LV with MD can be extend or not, so i don't c are the performance > and now is the error information(i didn't use lvextend before): > > [root@snap /root]# e2fsadm -L+1G /dev/raid-lvm/lv_raid > e2fsck 1.18, 11-Nov-1999 for EXT2 FS 0.5b, 95/08/09 > The filesystem size (according to the superblock) is 338944 blocks > The physical size of the device is 236544 blocks > Either the superblock or the partition table is likely to be corrupt! > Abort<y>? no seems you have some problem with the filesystem in /dev/raid-lvm/lv_raid did you play at reducing it before? yes, i use lvextend to extend it and then use lvreduce to reduce it, at last i use e2fsadm -L+1G /dev/raid-lvm/lv_raid i think the lvextend and lvreduce are no effect for e2fsadm thougt e2fsadm = lvextend then resize2fs if extending or resize2fs then lvreduce if shrinking Is it right? i don't know why it can't work. And now I mkfs the lv and use "e2fsadm -L+1G /dev/raid-lvm/lv_raid" it works well. thanks for your help,but i still puzzled why it can't work.
