I have/had Intel M25-E 32GB SSD drive as ZIL/cache device (2 GB ZIL
slice0 and the rest is cache slice1)
The SSD drive has failed and zpool is unavailable anymore.
Is there any way to import the pool/recover data, even with some latest
transactions lost?
I've tried zdb -e -bcsvL <pool name> but it didn't work.
Below are the details:
[r...@storage ~]# uname -a
SunOS storage 5.11 snv_129 i86pc i386 i86pc
[r...@storage ~]# zpool import
pool: neosys
id: 1346464136813319526
state: UNAVAIL
status: The pool was last accessed by another system.
action: The pool cannot be imported due to damaged devices or data.

zdb: can't open 'neosys': No such device or address
[r...@storage ~]# zdb -e -bcsvL neosys

Any help would be greatly appreciated.
