I am a Solaris Admin for the last 15 years, and a ZFS user from the very first public release. I think that hybrid storages (SSD+HD) are a huge opportunity for ZFS, but I am still seeing problem reports. Just a few days ago somebody posted in this list about being unable to delete a faulty SSD ZIL. I am trying to be cautious and apply due diligence. It is part of my job, after all... :) - -- Jesus Cea Avion _/_/ _/_/_/_/_/_/ j...@jcea.es - http://www.jcea.es/ _/_/_/_/ _/_/_/_/ _/_/ jabber / xmpp:j...@jabber.org _/_/_/_/ _/_/_/_/_/ . _/_/ _/_/_/_/ _/_/ _/_/ "Things are not so easy" _/_/ _/_/_/_/ _/_/_/_/ _/_/ "My name is Dump, Core Dump" _/_/_/_/_/_/ _/_/ _/_/ "El amor es poner tu felicidad en la felicidad de otro" - Leibniz -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.10 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQCVAwUBTmvH5Zlgi5GaxT1NAQLWCwP8Dv/YS1VSmIeCsOjF1IkFJO8TvyIodcPI AS/LaKWW2Px7QI/2ML6R4hX4Fylz1J3zBlAhIK7EAgCCrEJlmyPHkSdj9QskdWY+ gHfKMQCk0zkqtksC9WZSgrKHNYSOyI7PE0hDsZpJ35ai71IIZklJ/P+lSpEmPJZc opBiybNGlFQ= =pa2r -END PGP SIGNATURE- ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

[zfs-discuss] Scrubbing with faulted disk still physically attached
Hi, We've got faulted disk in ZFS mirror and hot spare active. Any experience of scrubbing in such scenario causing problems, since the faulted disk is still attached. We have been scrubbing all our pools once a week (heh, might be quite too often?) No scrub has taken place since the disk faulted on 6th of September and SMF activated hot spare. Faulted disk has been causing scsi bus resets during couple few days and we are unable to replace the disk for a week or so. Just wondering if the scrubbing could cause the faulted disk to screw up the SCSI bus because of IO heavy operations going on. As you can see our mirror can tolerate the other SCSI controller going down: NAME STATE READ WRITE CKSUM zonedata DEGRADED 0 0 0 mirror-0 ONLINE 0 0 0 c2t8d0 ONLINE 0 0 0 c5t8d0 ONLINE 0 0 0 mirror-1 ONLINE 0 0 0 c2t9d0 ONLINE 0 0 0 c5t9d0 ONLINE 0 0 0 mirror-2 ONLINE 0 0 0 c2t10d0ONLINE 0 0 0 c5t10d0ONLINE 0 0 0 mirror-3 DEGRADED 0 0 0 spare-0DEGRADED 0 0 0 c2t11d0 FAULTED 312 0 too many errors c2t13d0 ONLINE 0 0 0 39,4G resilvered c5t11d0ONLINE 0 0 0 mirror-4 ONLINE 0 0 0 c2t12d0ONLINE 0 0 0 c5t12d0ONLINE 0 0 0 spares c2t13d0 INUSE currently in use c5t13d0 AVAIL errors: No known data errors -- -Jussi Sallinen +358407007600 ju...@jus.si ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
