rmsf -x is it risky?

[Tim Medford]

I am eliminating some unused storage from our production system.  I have already removed all LVM structures from it, and have un-presented the storage from the EVA.  I am looking for a simple way to clean up all the stale device files that now say NO_HW during an ioscan.

Looks like the best option might be rmsf -x, but wondered if there's any risks in running that on a production system while it's live?  It will no do anything to the legitimate device files, correct?

Thanks in advance,

Tim

I normally avoid the cleanup and let a reboot flush them out, but that just me. if you must, your risk is limited to the human error involved.

rmsf -x is safe. Device files can always be recreated after they are removed (ioscan+insf) but can't be removed if the device is open (ie, LVM or VxVM, etc).
