Under OpenSolaris, each tracking entry for a deduped block (wh

Fletcher is fairly weak as things go, and so even though two checksums are the
same, there's a decent chance that the data is actually different. At least

Hi all,
After going from 8.2-RELEASE to 8-STABLE (to get ZFS v28), I get
log_sysevent: type 19 is not implemented
exactly 20 times during boot. What does that message mean? Need I worry

Dear colleagues,
any particular hints to tune FreeBSD NFS server for efficient work as a VMware
vSphere backend?
For now, I set up 16G amd64 with ZFSv28, 4k recordsize and no other particular
tuning, roundrobin lagg on 2 ems, mtu 9000. There are 4 WD RE3 1T disks as
AHCI, on raid10 ZFS config.
