I can't seem to get the read and write performance better than approximately 40MB/s on an ext2 file system. IMO, this is horrible performance for a 6-drive, hardware RAID 5 array. Please have a look at what I'm doing and let me know if anybody has any suggestions on how to improve the performance...

We recently had a strange NFS performance anomaly between a V880 running snv_124 and two NetApp filers. To investigate, a DTrace NFSv4 (and eventually NFSv3) client provider would been extremely helpful. Unfortunately, all I could find were a request for code review of a v3 client provider and another request for help developing a v4 provider. Nothing seems to have come from those initiatives,

When somebody is hammering on the system, I want to be able to detect who''s doing it, and hopefully even what they''re doing. I can''t seem to find any way to do that. Any suggestions? Everything I can find ... iostat, nfsstat, etc ... AFAIK, just show me performance statistics and so forth. I''m looking for something more granular. Either *who* the

just a quick update: no issues with NFSv4.0 (load is slowly growing, currently ~7k mailboxes) instead, bad news from delegation front, we enabled it for a couple of days but we ran in ugly issues: processes went in "uninterruptible sleep" state, load average gets huge, reboot was the only escape :-( -brd Alessio Cecchi wrote: > Il 12/06/2015 13:02, brd ha scritto: > >Alessio

Does anyone, is anyone running Xen on NFSv3 successfully? What are some of your pain points/success points? Have you tried a clustered file system with better results such as DRBD or GFS?

hi all, i'm managing a large installation of a dovecot cluster in director + NFS backend architecture and we are moving from NFSv3 to NFSv4. Our NFS server is a Netapp in clustered mode and reading technical specs of NFSv4 delegation feature it seems that enabling delegation in this type of dovecot architecture should bring great benefits: only one backend server access a specific mailbox at a

I ran the same dd tests from KnowYourNFSAlpha-1.pdf and performance is inconsistent and causes the server to become unresponsive. My server freezes every time when I run the following command: dd if=/dev/zero of=garb bs=256k count=64000 I would also like to mount a path like: /volume/some/random/dir # mount host:/gluster/tmp /mnt/test mount: host:/gluster/tmp failed, reason given by server: No

Hello, I set up NFSv4 server. To make sure I set vfs.nfsd.server_min_nfsvers=4. I can check its version, for example, by tcpduming and then I can see in wireshark lines like: Network File System Program Version: 4 V4 Procedure: COMPOUND.... .... is there any easier way to check its version? I see there is nfsstat -e option which shows delegs and locks. But all other ones are combined with nfsv3

Hi, I've a strange issue with the performance of file transfers between a Samba server and a Vista client. My configuration looks like this: fileserver: Samba 3.3 on FreeBSD 6.2 ----- gbit switch ----- workstation: Vista x64 When transfering files between the two PCs, I get abount 6.5 to 7 MB / sec. On my last Vista installation I got about 40 MB / sec. I've tried the following: -

Hi, We are running into a problem with a Samba setup and would like to know if a current fix or workaround is at all possible. Our setup is a NetApp filer serving NFS v4 that is mounted by Solaris and Linux servers. On those servers we are using Samba to create shares of those NFSv4 mounted filesystems. We are migrating to this NFSv4 setup from an existing Solaris NFSv3+Posix ACL setup that also

Hi everybody and thanks to those persons who make klibc being possible. I am booting a lessdisks system from a server. I have got it in NFSv3 but I would like use the features of NFSv4. I am using initramfs-tools so I have in my initrd.img the utility nfsmount wich make possible booting in NFSv3. I would like know if exists some version of nfsmount or some patch or, if does not, some program (a

I was used to integrate some linux client in my samba network mounting homes with 'unix extensions = yes', and works as expected, at least with some old lubuntu derivatives. Client side i use 'pam_mount'. Now i'm working on a ubuntu mate derivative, and i've not found a way to start the session properly in CIFS. If i create a plain local home (pam_mkhome), session start as

The problem you've described is definitely an NFSv3 problem.? The connections causing the client to hang are portmap connections. They're dynamic, and don't necessarily conform to /etc/services.

I am still having issues with new message count. When I move a message to another folder, it counts that message as new until you go into that folder. Is there a way I can solve this? Could it have something to do with NFS? I have tried all the NF workarounds with no luck... I have also tried NFSv3 and NFSv4, no difference. I store the indexes on the local drive...

Hello, I'm migrating from 1.1.16 running in 4 debian lenny servers virtualized with xenserver and 1 core and 5GB of RAM to 2.1.5 running in 4 ubuntu 12.04 servers with 6 cpu cores and 16GB of RAM virtualized with VMWare, but I'm having lots a performance problems. I don't think that virtualization platform could be the problem, because the new servers running in xenserver has
