It tries to use the same API for\next2, ext3, ext4, ReiserFS and XFS filesystem.\n\n### OPTIONS\n\n#### -e --ext-offline\n\nUnmount ext2/ext3/ext4 filesystem before doing resize.\n\n#### -f --force\n\nBypass some sanity checks.\n\n#### -h --help\n\nDisplay the help text.\n\n#### -n --dry-run\n\nPrint commands without running them.\n\n#### -v --verbose\n\nBe more verbose.\n\n#### -y --yes\n\nAnswer \"yes\" at any prompts.\n\n#### -c --cryptresize\n\nResize dm-crypt mapping together with filesystem detected on the device. The dm-crypt\ndevice must be recognizable by cryptsetup(8).\n\nnewsize[B|K|M|G|T|P|E]\nAbsolute number of filesystem blocks to be in the filesystem, or an absolute size us‐\ning a suffix (in powers of 1024). If newsize is not supplied, the whole device is\nused.\n\n### DIAGNOSTICS\n\nOn successful completion, the status code is 0. A status code of 2 indicates the operation\nwas interrupted by the user. A status code of 3 indicates the requested check operation\ncould not be performed because the filesystem is mounted and does not support an online\nfsck(8). A status code of 1 is used for other failures.\n\n### EXAMPLES\n\nResize the filesystem on logical volume /dev/vg/test to 1000 megabytes. If /dev/vg/test con‐\ntains ext2/ext3/ext4 filesystem it will be unmounted prior the resize. All [y/n] questions\nwill be answered 'y'.\n\n#### fsadm -e -y resize /dev/vg/test 1000M\n\n### ENVIRONMENT VARIABLES\n\nTMPDIR The temporary directory name for mount points. Defaults to \"/tmp\".\n\nDMDEVDIR\nThe device directory name. Defaults to \"/dev\" and must be an absolute path.\n\n### SEE ALSO\n\nlvm(8), lvresize(8), lvm.conf(5), fsck(8), tune2fs(8), resize2fs(8), reiserfstune(8),\nresizereiserfs(8), xfsinfo(8), xfsgrowfs(8), xfscheck(8), cryptsetup(8)\n\n\n\nRed Hat, Inc LVM TOOLS 2.03.11(2) (2021-01-08) FSADM(8)\n\n" } ], "structuredContent": { "command": "fsadm", "section": "8", "mode": "man", "summary": "fsadm — utility to resize or check filesystem on a device", "synopsis": "fsadm [options] check device\nfsadm [options] resize device [newsize]", "flags": [ { "flag": "-e", "long": "--ext-offline", "arg": null, "description": "Unmount ext2/ext3/ext4 filesystem before doing resize." }, { "flag": "-f", "long": "--force", "arg": null, "description": "Bypass some sanity checks." }, { "flag": "-h", "long": "--help", "arg": null, "description": "Display the help text." }, { "flag": "-n", "long": "--dry-run", "arg": null, "description": "Print commands without running them." }, { "flag": "-v", "long": "--verbose", "arg": null, "description": "Be more verbose." }, { "flag": "-y", "long": "--yes", "arg": null, "description": "Answer \"yes\" at any prompts." }, { "flag": "-c", "long": "--cryptresize", "arg": null, "description": "Resize dm-crypt mapping together with filesystem detected on the device.
