i am working with a FAS2050 with 2.4TB on each controller
yesterday we started to enable dedup 1 volume at a time (excluding vol0)
vol2 went from 412GB @ 96% to 63% (400GB lun)
whihc was a great start
today vol3 went from 415GB 94% to 100% (251GB lun) instantly and says snapshot creation failed
what would be the reason for this? there are no snapshot copies visable from oncommand
can yo give me some guidance on the commands?
i see there is an enable fractional reserver 100%
i am investigating that now i can just disable this yes?
okay thank you - i have taken off the fractional reserver whilst i run the dedup as there is plenty of space and no backups are performed using storage snapshots
when the dedup has completed i will re-enable
