Hey folks, While scrubbing, zpool status shows nearly 40MB "repaired" but 0 in each of the read/write/checksum columns for each disk. One disk has "(repairing)" to the right but once the scrub completes there''s no mention that anything ever needed fixing. Any idea what would need to be repaired on that disk? Are there any oth...

...ks 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: - raw tcp transfer rates with netio: 40MB/s with 1kb chunks up to 100MB/s with 32kb in both directions - upgraded Samba to the most current version of 3.3 (had 3.0 before) the port-system of FreeBSd will give me - set Vista tcp autotuner to disabled, normal and experimental (slight performance loss with disabled, about 500kb/s less) - s...

Snapshots are significantly faster as well. My average transfer speed went from about 15MB/sec to over 40MB/sec. I imagine that 40MB/sec is now a limitation of the CPU, as I can see SSH maxing out a single core on the quad cores. Maybe SSH can be made multi-threaded next? :) -- Brent Jones brent at servuhome.net

Hi, I have a server and ten clients in a Gigabit network. The server has 125mbps network bandwidth. I want that the server has 40Mbps bandwidth reserved for client 1 (IP 192.168.5.141), and the rest bandwidth is for all other clients. My script looks like this (I use IFB for incoming traffic): #!/bin/bash export TC="/sbin/tc" $TC qdisc add dev ifb0 root handle 1: htb default 30 r2q 100 $TC class add dev ifb0 par...

I'm seeing some really poor performance out of my FreeNAS (ver 9.10) machine, running Samba "4.3.6-GIT-UNKNOWN". I'm using IOMeter to benchmark sequential reads, and getting around 35-40 MB/sec, which seems unusual. Mostly, I'm hoping someone can point me in the direction of a decent tuning guide for a SOHO machine running Samba, but if you're inclined, I'll delve

Hello, I had some troubles with samba performance after I switched my network to gigabit ethernet: FTP gave 50MB/s (on a 5GB file) NFSv3 40MB/s (win xp client with SFU, free nfs client for windows) Samba (win XP client) only 15MB/s. After some fiddling with options, I found out that setting write cache size to 256KB resulted in a very big performance improvement, now also samba gabe 40MB/s. The documentation (man-page smb.conf) doesn...

A QSan P600Q-D316 Storage is configured with 8*SATA Drives raid 5 for test, connected trought a Cisco UCS 6100 Series Fabric Interconnect 10G Switch. I formated the storage with ext4 defaults, one volume and got r/w rates about 10MB/s some up to 40MB/s .... VERY POOR.... So we returned the storage to our dealer and they tested the hardware and did some IO Meter Test with VMware ESXi 5.1 Server -> virtual Windows 2k8-R2 on the Qsan Storage. The VM did some r/w IO Meter Benchmark up to 1000 MB/Sec. Better. Hardware looks o.k. Than they inst...

...insted of 2 wich I have been using for a while now... I did this when compiling... ./configure --prefix=/usr make Then when I checked the source/bin dir there was about 400mb of files there... It was the correct bin files but they were so huge that ther has to be something wrong.. Smbd was about 40mb... Anyone got some ideas on what I can do to make the files smaler? /Jonas

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.

We got a remote Oracle 10g R2 standby running on OCFS2. Initial when we started the standby, read I/O was < 5MB/sec on average. Since then it has grown to over 40MB/sec (longer average, it peaks much higher). Here is a graph showing this: http://www.alameda.net/~ulf/dbphx01.png We also have a local standby running (on EXT3) which is not showing the same symptom. I am trying to find where all these reads are happening. Anyone have an idea how to figure that o...

...s 7 and OS X) clients we never get really close to GBit speed on reads or writes. Using the same servers/storages with ftp, ssh, rsync, nfs we are on the max. of GBit or with the 10Gbit Storage/server on the max of the storage we currently own. (about 400MB/s) E.g. from my Mac Pro I get smb r/w +- 40MB/s, with ftp I get 90MB/s on a 1Gbit Server. So I try to eliminate some bottle necks. But where are they? I know there are some protocol overheads etc. comparing smb and e.g. ftp. So what kind of setup serverside may get better performance? What kind of Hardware are you using? Faster NICs (usual...

I know I can just add a larger disk but I would rather user the hardware I have if possible. 1) Is there anyway to replace the failed disk with one of the spares? 2) Can I recreate the zpool using 3 of the original disks and one of the slightly smaller spares?

...39;s terrific! I''m interested in doing memory oversubscription and am wondering if Xen can do this (now or in the future). For example, on a machine with 100MB available physical memory, can I: 1. Create a domain with a 90MB allocation 2. Inflate a balloon in that domain and return say 40MB back to Xen I know there are mechanisms for doing 1 and 2... 3. Allocate a second domain with an allocation of 50MB?

I have a backup server now restoring 6TB of data to a client machine. This has been going on for four days now, and no sign of getting close to completion. The connexion is Gb enet end-to-end, and is running at only 40Mb/s. It has far more capacity than that. The only limiting factor I can see is on the backup server one core of the CPU is running 100% rsync. Clearly rsync is not multi-threaded. In researching this I find that a change to multi-threaded goodness would require a massive rewrite, and would only b...

...tests with different filesystems settings, so currently we use ext4 and xfs (xfs e.g. for filesystems about 40 TB) And: We do backups, have BBUs and "all luxury" we can get and need. So my original question was focused: Why do I get r/w speed around 80-90MB/s with ftp or scp and only +-40MB/s on samba? I don't want to believe, that smb has such a biiiigggg overhead :) It is the same server, raid, filesystem, network konnection. In that Case 1Gbit from Client (OS X 10.9) -> Gbit Switch -> Server -> Storage. The Storage is connected to the server by a separate GBit VLAN....
