Dangerous to defrag twice at once? Dangerous to interrupt it?

[James]

Hello:

I manually started `gpmaintain` and it began to defrag my XFS volumes.

Falsely assuming that Ctrl+C would stop this, I did so, then (not knowing yet that defragging was what was happening) I again started `gpmaintain`.

It is my understanding that XFS defrag is capped at two hours but both are still running after three hours.

1) Is it dangerous to run two `xfs_fsr` processes on one drive simultaneously?

2) How (if at all) can I safely interrupt/stop one or both processes, across all Segment servers and drives?

Thank You,

James
