I have a question about filesystem alignment.
For example, I have a NetApp storage and physical RHEL host. I would like to add a virtual disk from storage to server over FC SAN.
After creating and mapping a LUN on storage I see a new block device in Linux.
I would like to create a LVM2 volume on it and create ext4 filesystem.
Should I use pvcreate with --dataalignmentoffset option?
Which sizes of physical extent should I use, while creating volume group to get better performance from storage array?
Which size should I put into blockdev --setbsz ? (default is 4096)
Should I create a lvm partition on raw device with fdisk and make physical volume on primary partition or use raw device to pvcreate?
Should I align partition with some sectors while creating in with fdisk?
Which sizes should I use for options stride and width_size in mkfs.ext4 ?
