You can certainly turn it off with any release (Jim's link). It's true that S10u4 does not have the "Separate Intent Log" to allow using an SSD for ZIL blocks. I believe S10U5 will have that feature. As noted, disabling the ZIL won't lead to ZFS pool corruption, just DB corruption (that includes NFS clients). To protect against that, in the event of a server crash with zil_disable=1, you'd need to reboot all NFS clients of the server (clear the client's caches) and better do this before the server comes back up (kind of a raw proposition here). -r > Thanks, > > Jon > > -- > > > - _____/ _____/ / - Jonathan Loran - - > - / / / IT Manager - > - _____ / _____ / / Space Sciences Laboratory, UC Berkeley > - / / / (510) 643-5146 [EMAIL PROTECTED] > - ______/ ______/ ______/ AST:7731^29u18e3 > > > > _______________________________________________ > zfs-discuss mailing list > zfs-discuss@opensolaris.org > http://mail.opensolaris.org/mailman/listinfo/zfs-discuss _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
