Re: Ok to resize XFS Volume with EVMS , loop AES256 crypted ?

[Christophe Zwecker <doc@zwecker.de>]

ok, I have this in fstab:

/dev/evms/store         /store          xfs 
defaults,noatime,noauto,loop=/dev/loop0,encryption=AES256 0 0

Yes I got

XFS filesystem -> loop -> EVMS -> raid5 disks

so I guess Ill try it with the swap device first to try or somthing

So it is no risk if the crypted device is disabled and I resize ?

thx alot

thx alot
