72 | tristate "Ext3 journalling file system support" | |
73 | help | |
74 | This is the journaling version of the Second extended file system | |
75 | (often called ext3), the de facto standard Linux file system | |
76 | (method to organize files on a storage device) for hard disks. | |
77 | ||
78 | The journaling code included in this driver means you do not have | |
79 | to run e2fsck (file system checker) on your file systems after a | |
80 | crash. The journal keeps track of any changes that were being made | |
81 | at the time the system crashed, and can ensure that your file system | |
82 | is consistent without the need for a lengthy check. | |
83 | ||
84 | Other than adding the journal to the file system, the on-disk format | |
85 | of ext3 is identical to ext2. It is possible to freely switch | |
86 | between using the ext3 driver and the ext2 driver, as long as the | |
87 | file system has been cleanly unmounted, or e2fsck is run on the file | |
88 | system. | |
89 | ||
90 | To add a journal on an existing ext2 file system or change the | |
91 | behavior of ext3 file systems, you can use the tune2fs utility ("man | |
92 | tune2fs"). To modify attributes of files and directories on ext3 | |
93 | file systems, use chattr ("man chattr"). You need to be using | |
94 | e2fsprogs version 1.20 or later in order to create ext3 journals | |
95 | (available at <http://sourceforge.net/projects/e2fsprogs/>). | |
96 | ||

1369 | If you want your Linux box to act as an NFS *server*, so that other | |
1370 | computers on your local network which support NFS can access certain | |
1371 | directories on your box transparently, you have two options: you can | |
1372 | use the self-contained user space program nfsd, in which case you | |
1373 | should say N here, or you can say Y and use the kernel based NFS | |
1374 | server. The advantage of the kernel based solution is that it is | |
1375 | faster. | |
1376 | ||
1377 | In either case, you will need support software; the respective | |
1378 | locations are given in the file <file:Documentation/Changes> in the | |
1379 | NFS section. | |
1380 | ||
1381 | If you say Y here, you will get support for version 2 of the NFS | |
1382 | protocol (NFSv2). If you also want NFSv3, say Y to the next question | |
1383 | as well. | |
1384 | ||
1385 | Please read the NFS-HOWTO, available from | |
1386 | <http://www.tldp.org/docs.html#howto>. | |
1387 | ||
1388 | To compile the NFS server support as a module, choose M here: the | |
1389 | module will be called nfsd. If unsure, say N. | |
