Hi list,
I just received a storage array and created a 3TB LUN with a block/sector size on the disks of 4096. When I boot the our centos-4.4 box attached to this array I get the "unsupported sector size 4096" message:
Remounting root filesystem in read-write mode: [ OK ] ERROR: unsupported sector size 4096 on /dev/sda. No RAID disks Setting up Logical Volume Management: [ OK ] Checking filesystems Checking all file systems. [/sbin/fsck.ext3 (1) -- /scratch] fsck.ext3 -a /dev/hdb1 /scratch: clean, 90/14663680 files, 485450/29304560 blocks [ OK ] Mounting local filesystems: [ OK ]
Any ideas as to why centos does not like the 4096 sector size on /dev/sda? What are the supported sector/block sizes in centos on disks/LUNs? Eventually I will be creating an LVM and ext3 file system on this. Any one know what the file system size limits on LVM/ext3 are?
Thanks in advance for any help on this.
Rene
