Please help me trouble shoot the RAID installation.
I am trying to concatenate 2 scsi drives of 50 GB each using software RAID
level 1 in Linux 6.1.
1. I created 2 raid partitions during installation on scsi drives a and
b. These are /dev/sda5 and /dev/sdb1 and of equal number of blocks.
2. created an /etc/raidtab file and rebooted the machine
3. did mkraid -f /dev/md0
4. entered the command for making the file system
A log of relevant info is attached.
As you can see, in step 4 I get a message "Invalid argument passed to ext2
library while setting up superblock."
What can I do to correct this situation?
TIA
Devaraj.

--force and the new RAID 0.90 hot-add/hot-remove functionality should be
used with extreme care! If /etc/raidtab is not in sync with the real array
configuration, then a --force will DESTROY ALL YOUR DATA. It's especially
dangerous to use -f if the array is in degraded mode.
PLEASE dont mention the --really-force flag in any email, documentation or
HOWTO, just suggest the --force flag instead. Thus everybody will read
this warning at least once :) It really sucks to LOSE DATA. If you are
confident that everything will go ok then you can use the --really-force
flag. Also, if you are unsure what this is all about, dont hesitate to
ask questions on [EMAIL PROTECTED]
