my 2 cents...
D-lexy,

I am curious about a few things. First, let me tell you what I have at work. I have an N-class server in full production mode. My /usr filesystem is only 1.6 GB. This is the standard for new Boxes in my corporate environment. All of my boxes are between 1.2 and 1.6 GB for /usr.

How much software/utilities do you have loaded on this box? 1.6GB seems like plenty to me. However, your case may be unusual.


Regarding your question about filesystem reworking of /usr, that can be very dangerous for OS filesystems. Normally you have to make a backup and then add disks and recreate the filesystems and then Re-load the OS. This is a simplistic description, but close. /usr is an OS filesystem.

You can usually add disks to an OS filesystem without too much problem. Just go to single user mode and make the necessary changes. However, to use a totally different disk for /usr requires much more work. At least it does in my environment.

I see the same thing when adding a whole disk LV to a separate device. It seems that when we expand a filesystem the inodes don't get tuned... (5 Replies)

findfs

FINDFS(8)						       System Administration							 FINDFS(8)

NAME

       findfs - find a filesystem by label or UUID

SYNOPSIS

       findfs NAME=value

DESCRIPTION

       findfs  will  search the block devices in the system looking for a filesystem or partition with specified tag. The currently supported tags
       are:

       LABEL=<label>
	      Specifies filesystem label.

       UUID=<uuid>
	      Specifies filesystem UUID.

       PARTUUID=<uuid>
	      Specifies partition UUID. This partition identifier is supported for example for GUID  Partition	Table (GPT) partition tables.

       PARTLABEL=<label>
	      Specifies partition label (name). The partition labels are supported for example for GUID Partition Table  (GPT)	or  MAC  partition
	      tables.

       If the filesystem or partition is found, the device name will be printed on stdout.

       The complete overview about filesystems and partitions you can get for example by

	      lsblk --fs

	      partx --show <disk>

	      blkid

EXIT STATUS

	      0      success
	      1      label or uuid cannot be found
	      2      usage error, wrong number of arguments or unknown option
