Convert individual Raid1 drive to standard Ext3 drive howto?
Hi,
In addition to my system drive /dev/hda (with all my standard
partitions /, /home. swap ... ), I have a raid1 device.
The raid is 2 - 250GB drives, with partitions /dev/hdb1 and /dev/hdc1
respectively (each the whole drive) each partitioned as linux fd (raid) type,
and configured as part of /dev/md0 as raid1.
I had formated /dev/md0 as ext3 and I have 250 gb of data stored on the raid.
Now I no longer need the data storage redundancy on that machine and would
like to treat the individual hard drives /dev/hdb1 and /dev/hdc1 as 2 copies
of the same data and move them separately to different machines.
Is there some way to convert from "ext3 file system set on top of a
degraded /dev/md0 device" to 2 separate devices
" ext3 file system on /dev/hdb1" and "ext3 file system on /dev/hdc1", without
copying to another drive...
I hope my question is clear...
Here is a circumstance that this might come up. I have 1 system and 4 data
hard drives on a workstation.
I like storing actively collected data on mirrored drives, while older data
does not need mirroring.
Thus initially I would like /dev/hdb1 and /dev/hdc1 to be mirrored
until /dev/hdb1 is filled up, then I would like to think of /dev/hdb1 as a
standard ext3 file sysem and let /dev/hdc1 and /dev/hdd1 mirror each other,
then when that fills, use /dev/hdb1, and /dev/hdc1 as ext3 while /dev/hdd1
and /dev/hde1 be mirrors.
I suppose I could let /dev/hdb1, and /dev/hdc1 persist as "degraded
raids /dev/md0 and /dev/md1, but that seems to be a overhead that wouldn't be
nice to carry around.
Thanks for your help!
Mitchell
