Folks,
Why can I not remove the ZIL from my zones pool? Please tell me
this is not a "feature"...
I'm trying to accomplish something that is ridiculously easy with
ZFS on Linux, and ridiculously difficult in SmartOS:
1. Partition my two SSDs to have two partitions each: one 2GB
partition for ZIL and one partition with all the remaining space for L2ARC
2. Set a mirror of the 2GB partitions on the two SSDs as the ZIL
3. Add the remaining space on the two drives as L2ARC space
I could do this in about 90 seconds on a Linux box: parted for step
1, "zpool add zones log mirror ssd1p1 ssd2p1" for step 2, and "zpool
add zones cache ssd1p2" + "zpool add zones cache ssd2p2" for step 3.
I've spent the last three hours trying to do it on my SmartOS box,
and now I'm stuck with a zones zpool that's using the full space on
both drives for ZIL with nothing left over for cache. And what's
worse, there's apparently no way to undo this without destroying the
zpool and starting over, which I absolutely cannot afford to do at
this point.
Any suggestions that anyone can make would be *very* welcome!
Hi,
Output of zpool status would be useful and command that you've tried to
remove the mirrored ZIL with.
This is what zpool(1m) says about removing ZFS Intent Log:
"Log devices can be added, replaced, attached, detached, and imported and
exported as part of the larger pool. Mirrored log devices can be removed
by specifying the top-level mirror for the log."
ie. zpool remove tank mirror-1
