The USB flash drive at 250m failed on March 5. I didn't notice it until Mar 6. I tried powering it up and down (tusb 1 0; tusb 1 1), and doing a soft reboot but it is still not mountable:
mount /dev/sda1 -t ext3 /tmp/usbdisk
mount: No medium found
fsck.ext3 /dev/sda1
e2fsck 1.35 (28-Feb-2004)
fsck.ext3: No medium found while trying to open /dev/sda1
Note: on the "flux" laptop there is now a "lsu" command (as on the DSMs) which does a ssh to each DSM and runs lsu there, so it is a quick way to check whether the internal archives are working.
250m has a flash drive, not a pocketec. I had 2 fail during testing in the staging area, which is quite unusual. They were not mountable on any system. There seems to be something about the titan usb port or the interface panel that is frying the flash drives.
With the duplicate data stream over the network, we did not loose any data from 250m (which was a bit lucky, since there was a problem with that too, which I also need to log).
As a workaround, 250m is now writing data to the compact flash drive (/media/cf). That has about 1.6 GByte available. One day's data for the 250m system is about 117 Mbyte, there is plenty of space.
Writing to /media/cf is enabled via a "bind" mount in $ISFF/projects/CABL/ISFF/scripts/dsm/other.sh
if [ $(hostname) == 250m ]; then
if ! mount | fgrep -q /media/usbdisk; then
mount --bind /media/cf /media/usbdisk

May want to do this on the other systems too, if this is going to be a problem in the future...
