Hi..
Thanks for your reply..Im sorry for not being clear... but its not just the filesystem that i want to expand. I need to expand the PV since i have increased the size on the LUN, for example.... /dev/sdb is LUN1 on the SAN, originally its size is 100G so is the PV... now i want to increase the size of LUN1 to 200G and i want Linux to see the changes without a reboot. In the past i have rebooted and run pvresize /dev/sdb for LVM to see the changes made to the PV. So my question is.. is there a way to update PV size after changing the size on the LUN without a reboot?
Thanks in advance.

At the moment the 880 is using 12 internal FC-AL disks as a db server and seems to be doing a pretty good job. It is not I/O, CPU or Memory constrained and the... (2 Replies)

mkfs.minix
MKFS.MINIX(8) Linux System Administrator's Manual MKFS.MINIX(8)
NAME
mkfs.minix - make a Linux MINIX filesystem
SYNOPSIS
mkfs.minix [-c|-l filename] [-n namelength] [-i inodecount] [-v] device [size-in-blocks]
DESCRIPTION
mkfs.minix creates a Linux MINIX file-system on a device (usually a disk partition).
The device is usually of the following form:
/dev/hda[1-8] (IDE disk 1)
/dev/hdb[1-8] (IDE disk 2)
/dev/sda[1-8] (SCSI disk 1)
/dev/sdb[1-8] (SCSI disk 2)
The size-in-blocks parameter is the desired size of the file system, in blocks. It is present only for backwards compatibility. If omit-
ted the size will be determined automatically. Only block counts strictly greater than 10 and strictly less than 65536 are allowed.
OPTIONS
-c Check the device for bad blocks before creating the file system. If any are found, the count is printed.
-n namelength
Specify the maximum length of filenames. Currently, the only allowable values are 14 and 30. The default is 30. Note that kernels
older than 0.99p7 only accept namelength 14.
-i inodecount
Specify the number of inodes for the filesystem.
-l filename
Read the bad blocks list from filename. The file has one bad block number per line. The count of bad blocks read is printed.
-v Make a Minix version 2 filesystem.
EXIT CODES
The exit code returned by mkfs.minix is one of the following:
0 No errors
8 Operational error
16 Usage or syntax error
SEE ALSO
mkfs(8), fsck(8), reboot(8)
AVAILABILITY
The mkfs.minix command is part of the util-linux package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/.
