Hi list,
using XFS on relatively big filesystems (> 8TB) I was wondering if it
is possible to estimate how much time an emergency "xfs_repair" would
take.
Some specific questions:
- will total time depend on how much the filesystem is filled (I think
so...)?
- will total time depend on how data are layed on the physical disks
(ie: fragmented vs sequential)?
- will total time scale down with increasing spindle count (ie: single
disk vs 4-way RAID10)?
On a related question: I generally use LVM to segregate/isolate my
virtual machine images. In this manner, even a completely blowed up
filesystem on one LV can not affect other LV.
How do you feel using a single big LV + XFS + preallocated RAW disk
images? Can a problem on the main XFS filesystem be contained on only
some VM files, or it really risks to destroy the entire filesystem?
Thank you all.
