Memory allocation problem in xfs

Latest response

I recently saw case about memory allocation deadlock on below cite.

https://access.redhat.com/solutions/532663

At this point solution seems cope with the high fragmentation. However, due to lack of knowledge for filesystem cache,
may I ask if using ext3 or ext4 can be another temporary solution where ? And if so why would it be the solution?

I am planning to build partitions on lvm with extent size of default 4MiB and block size default 4k.

Using ext3/4 might not be the solution. If your requirements don't exceed the default 4MB allocations then you should be fine to build with XFS. If fragmentation is an issue then there's a utility to defrag using [xfs_fsr] utility.
