Besides the one you mention, bug 6560174 also shows the problems I''ve seen with ZFS on firewire. (This bug also shows the blank status page.) Is there any way to know if these will be addressed?

I can''t see *any* part of 6560174 on bugs.opensolaris.org, which is somewhat annoying as it was me that filed it..... Fow what it''s worth though, ZFS on firewire seems to function reasonably well in spite of the transport reject errors I mention in that bug report. Pete.

This shows up on this summary page, but the details are blank: http://www.opensolaris.org/os/bug_reports/boo_list/ I see other bugs like this one that''s been open for 2 years. http://bugs.opensolaris.org/view_bug.do?bug_id=6276185 I know you get what you pay for, but is Solaris not serious about SCSI support?> Pete. > > Jeff Thompson wrote: >> Besides the one you mention, bug 6560174 also shows the problems I''ve >> seen with ZFS on firewire.

Apparently that''s now fixed and they should appear in a day or so.> Bug 6560174 ''multiple "transport rejected" messages when using zfs > with firewire disk'' shows the fatal > problem I''m having.

Note that these ''transport rejected'' messages are far less common when doing ufs IO to firewire drives (except sometimes during newfs), so it could simply be the case that zfs exercises the scsa1394 driver in different and less tested ways - I remember something similar with the SPARC ATA driver which would make the system virtually unusable during zfs writes. A fix would be nice though. And while we''re at it, so would multi- initiator firewire support along the lines of http://oraclenotes.com/ dba/RacLinuxFirewire.htm ... That would allow some nice, cheap but useful configurations for zfs/sun cluster development. Pete.

[comments about how firewire is becoming extinct > /dev/null :-)] Note: Solaris Cluster tends to expect SCSI reservations to work in order to prevent corruption. I would hope that firewire devices implement it... properly... -- richard
