Topic: Workstation Backup Failing on Ext USB

[gbentley]

Hi all,

Am back to an old problem I had on 7 - certain discs out of my collection of ext usb drives seem to go to sleep?

Error while mounting /dev/sdc1 /media/extusb :
mount: you must specify the filesystem type
Backup terminated: backup failed - status: 7424

If I then manually mount with '-t ext3' there will be a short delay, then the drive will mount/unmount as normal.

Someone on the old threads suggested sdparm - is sdparm available for 8?

I tried 'yum install sdparm' to no avail.

Or have you better suggestion?

Thanks!

Add the dag repo for sme8
http://wiki.contribs.org/SME_Server:Documentation:FAQ:Section01#Add_Dag_repository_to_SME_8_.28Centos_5.29

Then follow these generic instructions to install sdparm

ie
yum install --enablerepo=dag sdparm

Remember to use the Forum search function first before posting your query here, as this answer would have been easily found, eg search on sdparm

The search results where specific to 7

I tend towards the precautionary principle!

[Why the '?' - you are telling us something, not asking. ]

Sounds like this should be a bug report, and we should considering adding sdparm wakeup as a standard feature.

Hi Charlie, I was just raising the question over whether in fact it was the drive going into some kind of eco mode or if there is some other low level usb driver issue. I dont think I would know how to diagnose either.

Cheers,

See if using sdparm to wake the drive makes a difference. If it does, verify that using sdparm that way is harmless on other drives that don't go to sleep.
