IHAC who is using a very similar test (cp -pr /zpool1/Studio11 /zpool1/Studio11.copy) and is seeing behaviour similar to what we've seen described here; BUT since he's using a single-CPU box (SunBlade 1500) and has a single disk in his pool, every time the CPU goes into "100%-mode", interactive usability is reduced to zero for 1-2 seconds. This is of course undesirable.
+ Do we have any bug IDs or RFEs addressing this? + Is there any tuning the customer can try (he's willing to do anything with the machine, apart from donating it to me :-)? (we've already tried "echo txg_time/W1 | mdb -kw", with no improvement - on the contrary, machine returned to "usable" state hardly at all). + has customer (and I) missed a constraint about when/where to deploy zfs? thx Michael This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
