This is actually a VxVM question. I have a volume/filesystem spread over 4*146G disks. Now I want to shrink the filesystem - which I can do using vxresize. However, I want to shrink so that two of the four disks that the filesystem occupies are removed from the volume. Can I do that? (3 Replies)

RESIZE2FS(8) System Manager's Manual RESIZE2FS(8)
NAME
resize2fs - ext2/ext3/ext4 file system resizer
SYNOPSIS
resize2fs [ -fFpPM ] [ -d debug-flags ] [ -S RAID-stride ] device [ size ]
DESCRIPTION
The resize2fs program will resize ext2, ext3, or ext4 file systems. It can be used to enlarge or shrink an unmounted file system located
on device. If the filesystem is mounted, it can be used to expand the size of the mounted filesystem, assuming the kernel supports on-line
resizing. (As of this writing, the Linux 2.6 kernel supports on-line resize for filesystems mounted using ext3 and ext4.).
The size parameter specifies the requested new size of the filesystem. If no units are specified, the units of the size parameter shall be
the filesystem blocksize of the filesystem. Optionally, the size parameter may be suffixed by one of the following the units designators:
's', 'K', 'M', or 'G', for 512 byte sectors, kilobytes, megabytes, or gigabytes, respectively. The size of the filesystem may never be
larger than the size of the partition. If size parameter is not specified, it will default to the size of the partition.
Note: when kilobytes is used above, I mean real, power-of-2 kilobytes, (i.e., 1024 bytes), which some politically correct folks insist
should be the stupid-sounding ``kibibytes''. The same holds true for megabytes, also sometimes known as ``mebibytes'', or gigabytes, as
the amazingly silly ``gibibytes''. Makes you want to gibber, doesn't it?
The resize2fs program does not manipulate the size of partitions. If you wish to enlarge a filesystem, you must make sure you can expand
the size of the underlying partition first. This can be done using fdisk(8) by deleting the partition and recreating it with a larger size
or using lvextend(8), if you're using the logical volume manager lvm(8). When recreating the partition, make sure you create it with the
same starting disk cylinder as before! Otherwise, the resize operation will certainly not work, and you may lose your entire filesystem.
After running fdisk(8), run resize2fs to resize the ext2 filesystem to use all of the space in the newly enlarged partition.
If you wish to shrink an ext2 partition, first use resize2fs to shrink the size of filesystem. Then you may use fdisk(8) to shrink the
size of the partition. When shrinking the size of the partition, make sure you do not make it smaller than the new size of the ext2
filesystem!
OPTIONS
-d debug-flags
Turns on various resize2fs debugging features, if they have been compiled into the binary. debug-flags should be computed by adding
the numbers of the desired features from the following list:
2 - Debug block relocations
4 - Debug inode relocations
8 - Debug moving the inode table
-f Forces resize2fs to proceed with the filesystem resize operation, overriding some safety checks which resize2fs normally enforces.
-F Flush the filesystem device's buffer caches before beginning. Only really useful for doing resize2fs time trials.
-M Shrink the filesystem to the minimum size.
-p Prints out a percentage completion bars for each resize2fs operation during an offline resize, so that the user can keep track of
what the program is doing.
-P Print the minimum size of the filesystem and exit.
-S RAID-stride
The resize2fs program will heuristically determine the RAID stride that was specified when the filesystem was created. This option
allows the user to explicitly specify a RAID stride setting to be used by resize2fs instead.
KNOWN BUGS
The minimum size of the filesystem as estimated by resize2fs may be incorrect, especially for filesystems with 1k and 2k blocksizes.
