It depends on your definition of successful. I'm using 2.4.18 with
HIGHMEM and RAID 5 physical volumes, (and my chaining snapshot patch).
Existing snapshots seem to work OK under load, but I have trouble
creating the snapshots under load consistently. My problems are with
xfs_fs_freeze(), xfs's fsync_dev_lockfs implementation.
I have similar problems with 2.4.19. I've run with 2.4.20, but not
under load. Haven't tried 2.4.21 yet.
