Hi all- We've been experiencing a very strange problem for two days now. We have three client (Linux boxes) connected to a ZFS box (Nexenta) via iSCSI. Every few seconds (seems random), iostats shows the clients go from an normal 80K+ IOPS to zero. It lasts up to a few seconds and things are fine again. When that happens, I/Os on the local disks stops too, even the totally unrelated ones. How can that be? All three clients show the same pattern and everything was fine prior to Sunday. Nothing has changed on neither the clients or the server. The ZFS box is not even close to be saturated, nor the network.
We don't even know where to start... any advices? Ian -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
