Infrastructure Software

Hi,
I am using a Maxtor OneTouch 750GB USB disk as a backup device on an Ultra 60 which I am using as a destination for ZFS snapshots from another system.
The Ultra 60 is running Solaris 10 10/08.
I am using a Belkin PCI/USB card (F5U508).
The system has been fine for the past 2 weeks and each day for the last week I have been sending incremental snapshots e.g.
ptime zfs send -R -i @daily-13-03-2009 rpool/export/home@daily-14-03-2009|ssh root@host2 zfs recv -F -d backup/new

Then today I sent another and it just seemed to hang so I killed it after seeing a problem with the destination pool:-
host1{root}68: ptime zfs send -R -I @090306 rpool/export/projects@daily-13-03-2009|ssh root@host2 zfs recv -F -d backup
^CKilled by signal 2.

real 18:56.687
user 0.007
sys 0.019


Looking at the messages file on the destination server host2 I and see the drive has gone off-line:-

The zpool status now hangs.
rmformat now takes ages to return no devices :-(

Last week when the server was re-booted the zpool can on-line OK:-

Am I missing a patch for USB or ZFS which will fix this problem?

I am assuming the drive is OK but the system is remote and I will have to wait till the morning to call the office.

I could reboot the Ultra 60 and see if the zpool comes back to life but I wanted to see if anyone else had seen this problem.

Cheers
Richard
