raid

We have a server with 2x32gb sas raid 1 and 4x1tb raid 10 + 2x1tb hot spares. Whenever we try to copy the 1tb and 1.5e6 files to a backup location (even just using tty1 cp command) it fails.

We have tried using backintime and dejadup, and resorted to a manual cp to an external usb2 HDD. When that failed, we tried installing an internal HDD on the mobo (not on raid) and another cp, which also fails.

The failures lock up the system and we are left with an unfortunate hard reboot situation. After reboot, syslog tends to be empty (only containing newly booted data) and we haven't a clue where to start.

It has been 3 weeks since our last successful backup and we are getting nervous...

-using 3ware raid controller, 8gb ram and nvidia pciexpress graphics with a gigabyte mobo and xeon 4-core processor.

I have seen in some version of Ubuntu that instead of making a huge change to update to the latest kernel, they take some of the good stuff out of it, for the sake of stability and put it on a previous version. In this case, kernel 3.3 has seen some very good power management enhancements that are… >>> More
