[zfs-discuss] how to set mountpoint to default?

zfs set only seems to accept an absolute path, which even if you set it to the name of the pool, isn't quite the same thing as the default. see my other thread about "set mountpoint but don't mount?". ___ zfs-discuss mailing list zfs-discuss@opensolaris.o

Hello, My apologies if this has been discussed before or if this is the wrong place to discuss Solaris 10 U6 issues.. I am investigating using ZFS as a possible replacement for SVM for root disk mirroring. So far, I have installed the system with the new ZFS option in the text installer of U6.

Sounds like the device it not ignoring the cache flush requests sent down by ZFS/zil commit. If the SSD is able the drain it's internal buffer to flash on a power outage; then it needs to ignore the cache flush. You can do this on a per device basis, It's kludgy tuning but hope the instructi

Sogranted, tank is about 77% full (not to split hairs ;^), but in this case, 23% is 640GB of free space. I mean, it's not like 15 years ago when a file system was 2GB total, and 23% free meant a measely 460MB to allocate from. 640GB is a lot of space, and our largest writes are less than 5MB.

You have SSD's for the ZIL (logzilla) enabled, and ZIL IO is what is hurting your performance...Hmmm I'll ask the stupid question (just to get it out of the way) - is it possible that the logzilla is undersized? Did you gather data using Richard Elling's zilstat (included below)? Thanks, /ji
