I've been writing via tar to a pool some stuff from backup, around
500GB. Its taken quite a while as the tar is being read from NFS. My
ZFS partition in this case is a RAIDZ 3-disk job using 3 400GB SATA
drives (sil3124 card)
Ever once in a while, a "df" stalls and during that time my io's go
flat, as in :
capacity operations bandwidth
pool used avail read write read write

Is this an ARC issue or some sort of flush happening. This is B40.
