[snip] Journalling File Systems r like databases with rollback facilities in them, ofcourse they hav a whole plethora of advantages as compared to the traditional File Systems bering used on linux. One of the main advantages would have been that in case of a unorderly shutdown the Data Loss would have been minimised. Not the complete data loss can be prevented.
Look at Journallin File Systems as Databases with Rollback features in them. Journalling File Systems generally maintain a log of the changes to any meta-data that has to be commited to the disk. The meta-data is basically the information abt the data that u store on the disk. SO wheneever u perform a read/write trasaction the changes to the meta-data are recorded on a Journal which then becomed dirty. This is then commited to the disk in an orderly fashion when the syncing is done. So when there is as unorderly shutdown the data from the jounal log isn't flushed to disk.
Many a time in such situations u may witness loss of data regarding to the lost transaction since it hasn't been writen to disk. But remember, it's better than loosin ur whole File System.
As far as vouching about the sturdiness of ReiserFS, my personal experience on production systems say........it's good enough for most implementations. But yes, ONLY ONCE hav i seen a ReiserFS system go down........
as for ext3.......i don't care......
As of now....me nd my production systems run XFS, which is reaaaaaaaaly sturdy nad can support much larger file sizes. Check it out, i think the XFS port to Linux by SGI is one of the best thingz that has happened to Linux File Systems.
Yes my initial and the recent filesystem crashwas due to *power failure* Can I have more info 'bout journalling file system please
[snip] pliss refer to the above. As for the information on XFS and ReiserFS u can find info them @ www.freshmeat.net.
Actually I don't have separate partitions. Ihave this / and swap partition only.
[snip] as philip mentions, downgradin ur distro to 6.* wasn't the real solution. Some pple learn the hard way pal.
There's somethin that my dad always tells me,"When in DOUBT ASK".
I would like to add to it, "When in doubt ASK, but all GOOGLE."
I do this since my hard disk is just 4 gigs.I've read that you have to be real Linux guru
[snip] hehehehe...:)) The fact that u hav got so far means u hav achieved part gurudom..:))
to recover the lost+found data. So I did notbother about it. Can someone please give some info about recovering the data from lost+found
? [snip] just cd into those dirs u'll find the data lying all over the place in the form of files with inode nos.
P.S. I was really frustrated with the whole incident. I think that the subject line was little
provocative
and harsh.
[snip] Lets put this behind us. But next time before u say somethin, think abt the repurcussions it'll hav cause we believe in wat we work on and we hav tremendous faith in it. And trust and faith are virtues built over a loooooong period of time pal.
Being vociferous helps at times, but at times when looked at in a dim perspective can be detrimental.

crash due to power failures. Please guide me.
