I just started a parity check on my unraid server and I'm seeing a speed of around 30MB/sec (parity disk is a 6TB and data disks are a mix of 4TB reiserfs and 6TB xfs - SAS2LP cards on 16x PCIE v2.0). I remember before upgrading to V6 and with all reiserfs drives (also 6TB and 4TB) the parity check speed was much faster (average at the end around 100MB/sec - SAS2LP cards on 16x PCIE v2.0). Is there any news on this? Cheers Max

Looking with more attention to the syslog I've seen the following: Nov 14 18:30:31 MaxMe kernel: Hierarchical RCU implementation. Nov 14 18:30:31 MaxMe kernel: ^IRCU restricting CPUs from NR_CPUS=8 to nr_cpu_ids=1. Anyone knows it already? Cheers Max

Thank you eroz. Hoe someone can shed a little of light on that. Cheers Max

Thanks for taking time to answer. nproc gives me 1 Cheers Max

Hi everyone. I used the "lscpu" and "cat /proc/cpuinfo" and I got the following: lscpu cat /proc/cpuinfo Architecture: i686 CPU op-mode(s): 32-bit, 64-bit CPU(s): 1 Thread(s) per core: 1 Core(s) per socket: 1 CPU socket(s): 1 Vendor ID: GenuineIntel CPU family: 6 Model: 44 Stepping: 2 CPU MHz: 2405.486 Virtualization: VT-x L1d cache: 32K L1i cache: 32K L2 cache: 256K L3 cache: 12288K processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 44 model name : Intel® Xeon® CPU E5620 @ 2.40GHz stepping : 2 microcode : 0x13 cpu MHz : 2405.486 cache size : 12288 KB physical id : 0 siblings : 1 core id : 0 cpu cores : 1 apicid : 0 initial apicid : 0 fdiv_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 11 wp : yes bogomips : 4810.97 clflush size : 64 cache_alignment : 64 address sizes : 40 bits physical, 48 bits virtual power management: My CPU is an Intel Xeon E5620, shouldn't report 4 cores? Is there something wrong? Thanks for your help. Max

Hi, it is a couple of day that my unraid server, a small one not the one in the signature, has started a strange behavior. After it start I do "start array"and everything works fine, but after 15 / 20 minutes the samba, telnet and web stop responding saying the server is unreachable, while the console is still working (from there i can get to the disks or to the user share and see the files without problems). I attached the syslog where at the end there is - I suppose - the error but I haven't been able to understand much from it.

Here is the screenshot from the"Documents" users share. Thanks to take the time to look at it. Cheers Max

Hi all, I just upgraded a 4.7 to 5.0 and I got a strange issue. I got User Share enabled (attached picture 001.jpg) with no included or excluded hd setting. I have 5 share created and 4 are reporting the right amount of free space while one (Documents) is reporting a wrong free space amount (attached picture 002.jpg) All User Shares have "High Water" allocation mode and 0 free space settings Could anyone give me some suggestion to check if and what kind of problem this could be? Thanks! Max

Cheers Max

Is this exclusively related to this motherboard? I've got 8GB installed in a Supermicro C2SEA and haven't noticed this problem... Will have to go and test this now! On another note, I've successfully upgraded to RC10. Parity check has just completed successfully, and took pretty much the same time as on RC8a. EDIT: Forgot to mention, my board has a Realtek RTL8111C which seems to be working fine too.

I did a lot of test and try. Before I had speed of about 2,3 MB/sec in writing. Now I'm using RC10 Test and also using the 4095M memory parameter and everything seems back to normal. Cheers Max

I did check with ethtool eth0 command and I can confirm that the link is 1000 and full duplex. Doing more tests I noticed that copying to /mnt/disk2 I got for the first 7/8 seconds a speed of 30MB/s, after that it start to go at 2 MB/s. I'd like also to ask again if someone can share an old version of 5.0 RC so I could try it. Cheers Max

Updated, everything went fine. Unfortunately now I have a very slow writing speed. Copying a file from network (1gbit) to \\server\disk2\dir has a speed of about 2,3 MB/sec (megabyte/sec). How I can download a previous version? (5.0 RC) to check the speed in the previous version (I need 5.0 as I have only 4TB HD). UPDATE: I did few more tests. 1) Network copy > I confirm what I said before - speed around 2,3 MB/s writing to "disk..." share 2) Network copy > Copyng to cache drive get about 7,5 MB/s 3) dd command on "disk..." (/mnt/disk2) get 2,4 MB/s 4) dd command on cache (/mnt/cache) get 2,4 MB/s So it does look there is something wrong (attached my syslog) By the way parity check runs good at about 160 MB/s Any suggestion would be really appreciated. Cheers Max syslog.txt

I knew that to be the case, but I thought it was worth a check. I have seen this issue before but I'm drawing a blank on the answer. I have even had this myself.. when I added 4x m1015's it a took a few tries to get ESxi happy.. Thanks.. I think this is a good suggestion, I'll try with just one card and not all three at the same time...

VT-d is on in your bios? Thanks, I did check and it is. When VT-d is disable it is not possible at all to configure passthrough (edit button disabled). Cheers Max
