Shane,
Please take the following with some suspicion.
I used raidreconf to add drives to an array, so I assume
the grow functionality can at least do the same.
I wonder: if you have less than 1TB of data then you can:
1 fail one 320GB disk (array now degraded!)
2 use the port to install 1x1TB a

Hello all,
I have a raid5 softraid array using 6x320GB SATA drives. I
would like to reconfigure it to be 3x1tb SATA. Is there a
way to do this using the grow feature of mdadm. IE by
swapping 3 of the 320GB drives out for the 3 1TB drives
allowing the resync

Hi Andrew,
Are you sure your drives are healthy? Try benchmarking each drive
individually and see if there is a dramatic performance difference
between any of them. One failing drive can slow down an entire array.
Only after yo

If you have a full backup and a spare drive, I would probably rotate it
through the array.

Hello list,
some folks reported severe filesystem-crashes with ext3 and reiserfs on

Is this safe now? Or should i only use non-journalling-filesystems on

I have been using swRAID since it was an experimental patch, and ha
