why L2ARC device is used to store files ?
Greeting All
I have create a pool that consists oh a hard disk and a ssd as a cache
zpool create hdd c11t0d0p3
zpool add hdd cache c8t0d0p0 - cache device
I ran an OLTP bench mark to emulate a DMBS
One I ran the benchmark, the pool started create the database file on the
ssd cache device ???????????
can any one explain why this happening ?
is not L2ARC is used to absorb the evicted data
