Is there a good way to detect that particular disk went offline on server on Linux, via Java?
I have an application, that due to performance reasons, writes to all disks directly (without any RAID in middle).
I need to detect if Linux would unmount any disk due to disk crash during run-time, so I would stop using it. The problem is that each mount has a root directory, so without proper detection, the application will just fill-up the root partition.
Will appreciate any advice on this.
In Linux, everything is accessible through text files. I don’t really understand what is the exact information you require, but check
/proc/diskstat,/proc/mounts,/proc/mdstat(for raids), etc…
