I have a possible workaround. Mark Johnson <mark.john...@sun.com> has been emailing me today about this issue and he proposed the following:
> You can try adding the following to /etc/system, then rebooting... > set xpv_psm:xen_support_msi = -1 I have been able to format a ZVOL container from a VM 3 times while other activity is going on the system and it's working. I think performance is down a bit, but it's still acceptable. More importantly, it does so without killing the server. I would get the stall every time I would try this test before. So at least 1 case seems to be helped by doing this. I'll watch the server over the next few days to see if it stays improved. He mentioned that there is a fix being worked on for MSI handling in XVM that might make it into b129 that could fix this problem. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
