bdf,df,umount get hangs
Hi

how it can be recovered without rebooting and even after rebooting will it be solved.

Re: bdf,df,umount get hangs
You need to investigate why the server cannot longer access the (redundant) SAN - there must be a reason either on the switches or the array or somewhere between.
Hope this helps!
