[zfs-discuss] Should clearing the share property on a clone unshare the origin?

2012-09-25 Thread Ian Collins
I've noticed on a Solaris 11 system that when I clone a filesystem and change the share property: #zfs clone -p -o atime=off filesystem@snapshot clone #zfs set -c share=name= clone #zfs set share=name= clone #zfs set sharenfs=on clone The origin filesystem is no longer shared (the clone is s

Thank you for the link! Turns out that, even though I bought the WD20EARS and ST32000542AS expecting a 4096 physical blocksize, they report 512. The new drive I bought correctly identifies as 4096 byte blocksize! So...OI doesn't like it merging with the existing pool. Note: ST2000VX000-9YW1 rep

2012-09-25 Thread Jim Klimov
Hello all, With original "old" ZFS iSCSI implementation there was a "shareiscsi" property for the zvols to be shared out, and I believe all configuration pertinent to the iSCSI server was stored in the pool options (I may be wrong, but I'd expect that given that ZFS-attribute-based configs were
