Hello;
I have an existing, active ext3 filesystem which I would like to convert to
a RAID 1 ext3 filesystem with minimal down time. After casting about the web
and experimenting some on a test system, I believe that I can accomplish this
in the following manner.
- Dismount the filesystem.
- Shrink the filesystem to leave room for the RAID superblock at the end
while leaving the partition size untouched (shrinking by 16 blocks seems to
work )
- Create a degraded array with only the partition carrying the shrunk ext3
system
- start the array and mount the array.
- hot add the mirroring partitions.
The questions I have for those who know Linux-Raid better than I.
Is this scheme even half-way sane?
Is 16 blocks a large enough area?
Thanks in advance for any and all feed-back.
