Yes, there's two disks in the machine 1 x 500GB HD (root etc) and 1 x 60GB SSD which is the the pool we're having issues with. As you can see a full raw device dd completed fine. My admins tell me they have had a number of cases like this requiring a power cycle after which all is fine. Apparently it seems to affect machines with high uptimes, if thats of help. This machine shows:- uptime 1:55PM up 112 days, 3:19, 1 user, load averages: 0.00, 0.00, 0.00 Regards Steve ================================================ This e.mail is private and confidential between Multiplay (UK) Ltd. and the person or entity to whom it is addressed.
