I run ZFS sends all the time with COMSTAR on snv_134 over iSCSI VMware initiators. I do not have any dataset busy issues. Possibly the Linux client is using PGR and locking the LUN up perpetually. You need to capture the iSCSI traffic and examine/post what CDB's are issued by the Linux initiator. e.g. r...@ss1:~# snoop -d e1000g0 -o capfilename "10.10.10.1" Regards, Mike -- This message posted from opensolaris.org ___ storage-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/storage-discuss
