[reiserfs-list] Reiserfs and recovering from the format action...
Hi, if I format a reiserfs partition there are methods for recover it? Fabrizio.
Re: [reiserfs-list] Catastrophe with mailboxes on ReiserFS
What are those write barrier patches? and where can I find them? I was also hurted by several 'cross linked' files, described in here. is there a way to deactivate write caching for just one filesystem? regards, greg ps: please somebody let me know where I can find documentation about those chris mason patches, or at least what is dara=ordered or data=journal options. everybody talks about it, nobody explains. or did I miss something? I'd like to see these patches merged. I hurt myself several times with reiserfs, when the computer locked up during heavy file system activity, with NUL blocks in files, files mixed up and the like. I've never seen this on any data=ordered or data=journal file system, regardless of ext3 or reiserfs. Of course, write caches must be turned of or write barrier patches be applied to be safe in case of a power blackout. -- Matthias Andree

Some vendor kernels have them (SuSE), but I'm not sure where they are available ATM. hurted by several 'cross linked' files, described in here. is there a way to deactivate write caching for just one filesystem? No. You can only disable it per drive. ps: please somebody let me know where I can find documentation about those chris mason patches, or at least what is dara=ordered or data=journal options. everybody talks about it, nobody explains. or did I miss something? You can safely consult ext3 documentation on these options, reiserfs should behave the same in respect to these options. -- Matthias Andree

I would say that WAFL is an absolutely superb filesystem for the purpose of RAID NFS fileserving. Reiser4 may give it some serious competition after some time has passed and we have time for such things as carefully benchmarking NFS, etc., but WAFL is a great filesystem for NFS RAID as it is right now. That said, mp3.com saved $22 million dollars by using Linux+reiserfs instead of Netapps and Veritas. They may be good, but reiser3 is cheaper. A lot cheaper. Do the math, and you'll buy Linux instead I think.;-) Nobody has done reiser3 vs. WAFL benchmarks. Netapp as well have tons of features that linux boxes +PV210S can't do :Clustering volume copy, out out the box snapshots,etc.. Linux has snapshots if you use lvm, but it is true that Netapp makes a good product. | | Any comments on this setup is welcomed Now i think DELL realease their 220S with 14 disks in a shelf so that would have the bang for your bucks.

Hi, Yes, that's what i meant by not *out of the box* snapshots. We quite never played with LVM as it adds another software layer and i didn't feel it was mature enough at the time we put everything in production but given the benefits we might want to give it a try. BTW, Hans, what you would recommand : LVM or EVMS ?

I lack the expertise to advise on this. There has been a lot of controversy on this. Keep an eye out for lvm2 to come out. Hans

[reiserfs-list] ReiserFS Documentation
Hi, Can anyone point me to ReiserFS documentation? I have been through the whitepapers on www.namesys.com and some code. A more detailed note would be useful. TIA, Abhijit
