Manpages E2FSADMSection: Maintenance Commands (8)Updated: LVM TOOLS Index Return to Main Contents NAMEe2fsadm - ext2 filesystem / LVM administrationSYNOPSISe2fsadm [-d|--debug] [-h|--help] {[-l|--extents] [+|-]LogicalExtentsNumber| [-L|--size] [+|-]LogicalVolumeSize[kKmMgGtT]} [-n|--nofsck] [-v|--verbose] [--version] LogicalVolumePathDESCRIPTIONe2fsadm allows resizing of a logical volume containing a mounted or unmounted ext2 filesystem. For unmounted filesystems it can extend the logical volume and grow the filesystem using resize2fs(8) or ext2resize(8), or shrink the filesystem and then reduce the logical volume afterwards. For mounted filesystems it can extend the logical volume and grow the filesystem using ext2online(8).OPTIONS
DIAGNOSTICSe2fsadm calls e2fsck(8), lvextend(8), lvreduce(8), and resize2fs(8), ext2resize(8), or ext2online(8) internally. By default, for mounted filesystems e2fsadm will look for resize2fs first, and failing that it will look for ext2resize. For mounted filesystems it will try to run ext2online. It returns an exit code of 0 for success or > 0 for error:1 the filesystem size is invalid 2 the logical volume name is missing 3 the logical volume name is invalid 4 the logical volume doesn't exist 5 an error occured while reading the VGDA 6 an error occured while resizing the filesystem 7 /proc/mounts is not available 8 the filesystem is mounted 9 the filesystem type is not ext2 10 the e2fsck(8) command is missing or was not found 11 resize2fs(8) is missing or was not found 12 unable to run e2fsck(8) 13 unable to run resize2fs(8) 14 an error occured while reading the logical volume 15 logical volume size error 16 lvextend(8) is missing or was not found 17 unable to run lvextend(8) 18 lvreduce(8) is missing or was not found 19 unable to run lvreduce(8) 95 driver/module not in kernel 96 invalid I/O protocol version 97 error locking logical volume manager 98 invalid lvmtab (run vgscan(8)) 99 invalid command line ENVIRONMENT VARIABLES
