 |
|
All:
Did
mkraid /dev/md4
mke2fs -j /dev/md4
Now when I do
e2fsck -f /dev/md4
I am told the superblock is corrupted. What do I do? Thank you for your assistance.

P.S.: Want to clarify that RAID array created with 2 partitions that already had ext3 filesystems on them, if that matters. I am adding software RAID to an existing installation, trying not to loose any data in the process. |

First of all, what is your kernel, is raid compiled as modules or builtin, what does the /proc/mdstat say? maybe it is synching and don't let you fscheck.

The kernel is vanilla with raid compiled in and modules md and raid1 loaded. Too late to check /proc/mdstat during syncing but I refer you to
http://www.linuxjournal.com/article.php?sid=5653
steps 7 and 8 to support the claim that e2fsck is valid during syncing. Same result when syncing is finished, though.
