[WBEL-users] Errors mounting raid device

[Simone]

Hi, and really thank you so much for your reply.

If you have time, just some quick more questions. I started the array, then
partitioned with fdisk (chosed primary, 1 partition 200Gb, type 83),
rebooted.
Checked fdisk printed the right partition, ok, I get /dev/md3p1 (means it is
extended? I choosed a primary partition.....)
Then I run mke2fs -j  /dev/md3, it all seems to work but then if I run fdisk
I find "Warning invalid flag 0x0000 of partition table 4", and if I ask
fdisk to print the table it looks like no partition is defined.
Then I run e2fsck -nf /dev/md3    it says couldn't find ext2 superblock.
trying backup blocks..... /dev/md3 was not cleanly unmounted, check forced.
And then a list of errors
Inode 16777569 is in use, but has dtime set. Fix?
Inode 16777569 has imagic flag set. Clear?
And so on.
Does it make any sense to anyone? I'm now checking for bad blocks, even if
the disks are new maxtor 200 Gb ATA133 on Promise controller 20265 onboard.
I've read a lot on this controller and there are different opinions on
it......should I go for a 3ware card?
I also red thet ext3 is slower than reiserfs, any opinion on it?

Thanks again for your time
Simone
