mainstorage 29.1T 23.8T 5.31T 67% 81% 1.00x ONLINEAs you would imagine, it's slow, super slow! Are there any way of fixing fragmentation while being online? I've been thinking about shutting it all off, then make a clean backup of everything to PBS - nuke the mainstorage and recreate it (with larger disks) and then restore from PBS... but it would take some time with 20+ TB data and slow disks.
