^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 7) The following mount options are supported:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 8)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 9) (*) == default
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) iocharset=name
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) Character set to use for converting from Unicode to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) ASCII. The default is to do no conversion. Use
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) iocharset=utf8 for UTF-8 translations. This requires
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) CONFIG_NLS_UTF8 to be set in the kernel .config file.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) iocharset=none specifies the default behavior explicitly.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18) resize=value
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) Resize the volume to <value> blocks. JFS only supports
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) growing a volume, not shrinking it. This option is only
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21) valid during a remount, when the volume is mounted
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) read-write. The resize keyword with no value will grow
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23) the volume to the full size of the partition.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25) nointegrity
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26) Do not write to the journal. The primary use of this option
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27) is to allow for higher performance when restoring a volume
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28) from backup media. The integrity of the volume is not
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29) guaranteed if the system abnormally abends.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 30)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 31) integrity(*)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 32) Commit metadata changes to the journal. Use this option to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 33) remount a volume where the nointegrity option was
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 34) previously specified in order to restore normal behavior.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 35)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 36) errors=continue
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 37) Keep going on a filesystem error.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 38) errors=remount-ro(*)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 39) Remount the filesystem read-only on an error.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 40) errors=panic
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 41) Panic and halt the machine if an error occurs.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 42)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 43) uid=value
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 44) Override on-disk uid with specified value
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 45) gid=value
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 46) Override on-disk gid with specified value
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 47) umask=value
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 48) Override on-disk umask with specified octal value. For
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 49) directories, the execute bit will be set if the corresponding
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 50) read bit is set.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 51)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 52) discard=minlen, discard/nodiscard(*)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 53) This enables/disables the use of discard/TRIM commands.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 54) The discard/TRIM commands are sent to the underlying
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 55) block device when blocks are freed. This is useful for SSD
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 56) devices and sparse/thinly-provisioned LUNs. The FITRIM ioctl
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 57) command is also available together with the nodiscard option.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 58) The value of minlen specifies the minimum blockcount, when
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 59) a TRIM command to the block device is considered useful.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 60) When no value is given to the discard option, it defaults to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 61) 64 blocks, which means 256KiB in JFS.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 62) The minlen value of discard overrides the minlen value given
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 63) on an FITRIM ioctl().
