Hello
in var log messages i get following : kernel: XFS: possible memory allocation deadlock in kmem_alloc (mode:0x250) I have this problem on 4 different hosts. This happens during copying files from network to a thin provisioned disk, no problems with preallocated disks.

In such a case, it may take a lot of time before all the initialization is finished.
