When mounting an ext3 filesystem, the following option are accepted:
(*) == default
+ro Mount filesystem read only. Note that ext3 will replay
+ the journal (and thus write to the partition) even when
+ mounted "read only". Mount options "ro,noload" can be
+ used to prevent writes to the filesystem.
+
journal=update Update the ext3 file system's journal to the current
format.
identified through its new major/minor numbers encoded
in devnum.
-noload Don't load the journal on mounting.
+norecovery Don't load the journal on mounting. Note that this forces
+noload mount of inconsistent filesystem, which can lead to
+ various problems.
data=journal All data are committed into the journal prior to being
written into the main file system.
debug Extra debugging information is sent to syslog.
-errors=remount-ro(*) Remount the filesystem read-only on an error.
+errors=remount-ro Remount the filesystem read-only on an error.
errors=continue Keep going on a filesystem error.
errors=panic Panic and halt the machine if an error occurs.
+ (These mount options override the errors behavior
+ specified in the superblock, which can be
+ configured using tune2fs.)
+
+data_err=ignore(*) Just print an error message if an error occurs
+ in a file data buffer in ordered mode.
+data_err=abort Abort the journal if an error occurs in a file
+ data buffer in ordered mode.
grpid Give objects the same group ID as their creator.
bsdgroups
sb=n Use alternate superblock at this location.
-quota
-noquota
-grpquota
-usrquota
+quota These options are ignored by the filesystem. They
+noquota are used only by quota tools to recognize volumes
+grpquota where quota should be turned on. See documentation
+usrquota in the quota-tools package for more details
+ (http://sourceforge.net/projects/linuxquota).
+
+jqfmt=<quota type> These options tell filesystem details about quota
+usrjquota=<file> so that quota information can be properly updated
+grpjquota=<file> during journal replay. They replace the above
+ quota options. See documentation in the quota-tools
+ package for more details
+ (http://sourceforge.net/projects/linuxquota).
bh (*) ext3 associates buffer heads to data pages to
nobh (a) cache disk block mapping information
