I'm using a lot of RAID1 with ext3 ontop in my virtual servers and i resize (grow) the RAID1 and ext3 filesystem as i need more space without interrupting. I've done this very often (more than 50 times) for a long time (for about 2 years) and never had any problems. I also do sometimes fsck to check if something went wrong (i can do this without interruption because my RAID1 partitions are managed with lvm, and so, i do snapshots and make the fsck on the snapshots). I've done shrinking not that often because i don't know a filesystem which can shrinking online (ext3 and reiserfs can be shrinked offline). But as i've testet shrinking with ext3 it's for me also very stable. Shrinking reiserfs (offline) doesn't work reliably and i use reiserfs only on my backup space. But shrinking RAID1 is not possible without recreating the RAID1, means shrinking RAID1 is not possible online. -- greetings eMHa
