DAY 2 LISA 2010 ZFS tut
08 Nov 2010
Day two the rain has stopped a little bit of Californian sunshine.
Doing Richard's ZFS tut. 2 thumbs up so far.
Would you believe I didn't know you could set the number of copies zfs keeps of a file, cool learning stuff.
My random notes that won't make sense to anyone but me :-)
zfs set copies=# name
zpool set dedupditto=2 zwimming
2 turns out to be a good setting
zpool set dedup=on,verify zwimming
By deafult verify is not on, always turn on verify
zdb -DD rpool
show depup DDT
zdb -S rpool
Simulate dedup DDT
zfs send -DR zwimming/stuff
Send with dedup
zpool history rpool ( -l option to show user info)
Can have user defined properties.
vscan property can point zfs at an icap server for Virus scanning http://wiki.genunix.org/wiki/index.php/Implementing_vscan_service_with_ClamAV_on_ZFS
zfs_vdev_max_pending perhaps 2 for SATA perhaps 4000 for large hardware raid arrays?
