Data integrity tool...?
I've been looking for a good data integrity test tool for linux, but I'm having trouble finding one. Basically I'm looking for an application that will generate a heavy I/O load to a raw device and then perform some kind of data verification on the device. I my case the raw device will be md raid5 array. Any suggestions?
will overwrite the whole <DEVICE> four times with these patterns: 10,01,11,00
badblocks -svw <DEVICE>
After each write, there is a read of the whole device.
So this takes a while.
The option -w will do _writes_
So all data on the device will be overwritten and lost.
Thanks, I'll give that a try.
