We think that our server currently has a hardware problem.
Do you know if it is possible to do a stress test of the hard drives with Open-E?
For example, we did a stress test on a FreeNAS system with IOzone.
Is there something similar to this for Open-E?
We do not have this built into the OS, however, you may run any test you wish from an attached OS by iscsi, or NFS, SMB etc.
It may also be best to connect to the RAID controller directly and check to see if there are any current problems. (i.e. megaraid storage manager, Adaptec MaxView, etc)
