From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0) Description of problem: Hi, I have a fresh RH 7.1 (2.4.2-2smp i686) install on a Compaq DL360 with the embedded Smart Array controller. I have partitioned the remainder of my disks with fdisk and rebooted. I now need to setup my extra disks and filesystems with an 8k block size for use with an Oracle database. If I use mkfs.ext2 -b 8192 /dev/ida/c0d0pN it says 8192 is a bad block size?!! I can successfully use mkfs.ext2 -b 4096 /dev/ida/c0d0pN. I can also successfully use mkfs -V /dev/ida/c0d0pN which uses a 4k filesystem blocksize by default. How reproducible: Always Steps to Reproduce: 1.mkfs.ext2 -b 8192 /dev/<put your partition here> 2. 3. Actual Results: mkfs.ext2: bad block size - 8192 No filesystem is created. Expected Results: It should have created a new 8k block ext2 filesystem. Additional info: I suspect this is not RedHat specific, as I get the exact same problem with SuSE 7.2 on the same hardware. you may have to check with the mkfs.ext2 developer?
Only up to 4K blocksize are supported. Florian La Roche
