Ext2]
is the Extended Filesystem,
version 2. It
grew out of the [MinixFS], which had some very strict limitations.
-Ext2 was the filesystem which everyone
used for Linux for many many years, however, it's new successor
[Ext3
] has started
to become popular
.
+[
Ext2]
used to be the default FileSystem
for almost every [
Linux] box
for many many years. It is rock-solid and has an excellent fsck(8) which can recover from most situations. Very little data has been lost from
[Ext2
] partitions, even though it
has no journalling support. Another problem is that its directory handling doesn't scale well
to large directories
.
-Ext2 in particular has no journalling support
, and is bad at handling directories
with huge numbers of entries. (Over 1,000 or so)
.
+Therefore
, with growing HardDisk capactites its new successor [Ext3] with journalling support has become popular
.
-Ext2 has an excellent fsck which can recover from most situations, since Ext3 is very similar to Ext2 it
also uses fsck, even though it doesn't necessarily need to, since it has a journal.
-
--- not true! The journal helps recover from a crash, as you know where you were writing to when the power failed, so you can check only the affected files
. However, ext3 partitions still get checked irregularly (eg mount counts, time limits) to ensure that the file
-system is consistent
. Hard drive errors can still introduce problems. -- JohnMcPherson
