During today's attempts to make filesystem on a 15 TB virtual drive (RAID60) built on top of MegaRAID SAS 2108 from 4Tb SAS 7.2K drives I figured that each time I am receiving the following error :
ext2fs_mkdir: Attempt to read block from filesystem resulted in short read while creating root dir
I had IDC technical support to reseat the controller, check all SAS cables to disks, reseat the disks, which were marked as Failed after receiving the above error message. Also, I have tried: - create filesystem on partitioned device : /dev/sdb1; - create filesystem on LVM on top of PV, which contains of /dev/sdb - add disks in RAID50 and create filesystem on both device and LVM. Btw, command, which I am using to create filesystem is:
mkfs.ext4 -L home /dev/vg00/lv_home
My special suspect is put into "Background initialization" process, seen in Virtual drive info:
and that this virtual drive is in inconsistent state:
MegaRaid documents are telling the following about "Background Initialization" and I cannot get if it is 100% necessary to be completed before further operations with drive or not:
Perhaps, someone can advise on why filesystem fails to be created there and if I really need to allow "Background Initialization" process to finish before creating fs?
