Hello,
I am running a fileserver with SuSE SLES10 on it that has a 5TB RAID6 device
attached to it. The RAID has 1GB cache memory (battery backed up). Ob this
raid device I use EVMS to manage the space available. There will be several
evms volumes with xfs on them on this raid and I ask myself if there are any
hints how to create the optimal filesystem with high read and write
performace. Or is it sufficient to stay with the defaults mkfs.xfs provides?
The filesystem have a size that range from 50GB to 500GB and mostly contain
user home directories, i.e. they will probably contain a lot of small files.
One point I think about is if it would make sense to create the xfs
filesystems using an external logging device. Does anyone have experience in
this? How big should the log be compared to the filesystem? Is it possible to
change the loggining mode of an existing XFS filesystem from internal to an
external device without recreating (destroying) it?
Can anyone comment on this?
Thanks
Rainer Krienke
