Greetings,
I have a Dell 2300 running RH 6.2 that's been happily going a couple years
running apple's quicktime streaming server software.
Its set up with raid 5 w/parity on the three drives using hardware raid via
megaraid v107. I added a 4th drive and found a utility called MegaMgr on
the web and added the 4th physical drive to the logical drive then
reconstructed the raid and judging by disk light activity the
reconstruction worked and it is writing to all 4 drives in the array.
However, df doesn't reflect any difference in avail storage. My other
PowerEdge servers all have perc2 and I haven't found any useful docs on the
megaraid, I am at a loss at how to make the os see the actual new size of
the logical drive, Is anyone familiar with the megaraid and the megamgr
util? I must be missing some step to make the os see that the logical drive
grew by 36gig? any suggestions appreciated!!
dmesg snippit follows:
