Hi, I tried to do lvextend and then lvreduce (same space) without unmounting the file system, bcoz of online read/write operation on that file system. System seems slow (almost hanged). So can anybody please tell me whether the SAME extended block is reduced by the lvreduce command or not. And what could be the reason of system hang. -- Regards, Chitaranjan 91-4510701/02 Ext -3159 " Make sincerity and innocence as your real strengths !!
