4K blocks gives between 80 and 90% usage on any 3390 device. Mod-27 changed the number of cylinders/tracks, it didn't change the size of a track, as far as I know.
8K blocks will gain a little more usage per track. -----Original Message----- From: Linux on 390 Port [mailto:[EMAIL PROTECTED] Behalf Of David Booher Sent: Friday, April 16, 2004 11:29 AM To: [EMAIL PROTECTED] Subject: [Possible Spam] Mod-27 with SLES8: blocksizes I just formatted a new "mod-27" with dasdfmt -b 4096. I was shocked to see: /dev/dasdg1 23216892 20 22037520 1% /mnt 23.2 Gb??? The mod-27 is supposed to have 25.9 Gb of space. Is there a better blocksize to use without wasting 2.7 Gb of space?
