[CentOS] cachefs efficiency
Hi We are testing out the efficiency of cachefs and I was wondering what values other people use to decide if * cachefs is providing value? * cache size is the right/best/optimal size? * There is enough cache hits to make it worth while? * what files are being re-used(read from cache) the most? * how do I know if file are being opened with directIO ? I have access to /proc/fs/fscache/stats and /proc/fs/fscache/objects But the documentation is not clear in fscache.txt Thanks in advance.

Re: [CentOS] cachefs
I don't know why they weren't in the release notesmaybe because it's a preview release? They were issues in the Kernel. If you have a look at the output of rpm -q kernel -changelog|less you can see a whole swag of changes in 2.6.32-405.el6 On 03/04/14 12:34, Rita wrote: > thanks for your response. > > How come I don't see any changes in the Centos 6.{3,4,5} release which > mention updates to cachefs? > > > > On Wed, Apr 2, 2014 at 7:22 PM, grants wrote: > >> We are using CentOS 6.5 and it has been very stable. >> we were hit with bugs in 6.2 6.3 and 6.4. >> >> >> >> -- >> View this message in context: >> http://centos.1050465.n5.nabble.com/CentOS-cachefs-tp5724928p5725725.html >> Sent from the CentOS mailing list archive at Nabble.com. >> ___ >> CentOS mailing list >> CentOS@centos.org >> http://lists.centos.org/mailman/listinfo/centos >> > > ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] cachefs
thanks for your response. How come I don't see any changes in the Centos 6.{3,4,5} release which mention updates to cachefs?

Re: [CentOS] cachefs
Yes, compiler cache is different. I suppose I should ask is there something similar to cache?

In the last year we had two system freezes caused by cachefs. Its still a tech preview. the nfs client performance is significant better with cachefs enabled. -- LF ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

thanks steve. seems like we are in the same boat.

Re: [CentOS] cachefs
https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux/6/html-single/Storage_Administration_Guide/#rhel6storage-whatsnew fs-cache is a tech preview(Zero support from redhat). Tried cachefs on a few servers(don't remember if it was rhel 6.1 or 6.2 at the time), had problems (server hanging/unresponsive), asked redhat for support, was denied support, removed cachefs. Unsure if newer versions are more stable.("fool me once" kind if thing) > On Mar 1, 2014, at 7:48 AM, Rita wrote: > > has anyone been using cachefs with 6.x series? i have tried using it but i > keep getting hung processes after 2 weeks. > > ATM, running 6.3 but was curious if its more stable on Centos 6.5? > > -- > --- Get your facts first, then you can distort them as you please.-- > ___ > CentOS mailing list > CentOS@centos.org > http://lists.centos.org/mailman/listinfo/centos ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
