Hi ;
I dont think that anyone owns the list and as anyone else you are very
welcome to ask any question.
L2arc will cache zpool so if your iscs lun is a zvol or a file on zfs
it will be cached.
Please use constar if you need performance
You are correct that you will only need couple of gb as zil.
Performance gain of using a portion of ssd for l2arc will depend on
your pool configuration, your average load mix.
A side note: use raid 10 if you are using zfs and iscsi and need
random iops

Hi all,
Sorry for spamming your mailinglist,
but since I could not find a direct awnser on the internet and
archives, I give this a try!
I am building an ZFS filesystem to export iSCSI LUN's.
Now I was wondering if the L2ARC has the ability to cache non-
filesystem iscsi lun's?
Or does it only work in combination with the ZFS mounted filesystem?
Next to that I am reading all kind of performance benefits using
seperate devices
for the ZIL (write) and the Cache (read). I was wondering if I could
share a single SSD between both ZIL and Cache device?
Or is this not recommended?
This because the ZIL needs 1 GB top from what I read?
But since SSD is not cheap, I would like to make use of the other
GB's on the disk.
Thank you.
Armand
