I did remove and added devices again, with:
'zpool remove tank gpt/l2arc1 gpt/l2arc2'
and then
'zpool add tank cache gpt/l2arc1 gpt/l2arc2'
I left it running overnight and the same situation occured.
cache - - - - - -
gpt/l2arc1 175G 16.0E 11 106 55.5K 9.75M
gpt/l2arc2 167G 16.0E 14 107 68.8K 9.81M
For faster filling of the l2arc I also had 2 systcl's set:
vfs.zfs.l2arc_write_max: 33554432
vfs.zfs.l2arc_write_boost: 33554432
I do not plan to use this for production, only in testing.
