I have found the max number it can get to depends on the disk/mfg. Older seagates only did 512, newer 1.5's could get to 4096 if I am remembering correctly. I do know for sure that the newer disk I had went much higher before the disk itself officially failed. I have found disks that aren't reporting re-allocates, but respond poorly, and seem to be hitting close to the 7 second timeout and cause large IO pauses, and it is just best to replace the disk when it starts acting up like that.

After this, the named disk was replaced and the new disk added to the raid. Things work now, and I (or we) have learned that if given flag climbes this quickly, better replace the bugger in the first place :) > > Vennlig hilsen > > roy > -- > Roy Sigurd Karlsbakk > (+47) 98013356 > http://blogg.karlsbakk.net/ > GPG Public key: http://karlsbakk.net/roysigurdkarlsbakk.pubkey.txt > -- > Hið góða skaltu í stein höggva, hið illa í snjó rita.
