[zfs-discuss] Is Dedup processing parallelized?

2011-05-20 Thread Jim Klimov
Hi all, On my oi_148a system I'm now in the process of evacuating data from my dcpool (an iSCSI device with a ZFS pool inside), which is hosted in my physical pool on harddisks (6-disk raidz2). The dcpool was configured to dedup all data inside it, and the volume pool/dcpool was compressed as to
