similar to: ZFS/NFS/LDOM performance issues

To improve the performance of scripts that manipulate zfs snapshots and the zfs snapshot service in perticular there needs to be a way to list all the snapshots for a given object and only the snapshots for that object. There are two RFEs filed that cover this: http://bugs.opensolaris.org/view_bug.do?bug_id=6352014 : ''zfs list'' should have an option to only present direct

Hello, I''m a grad student working at University of Michigan in computer architecture. I''m writing to open up the idea that instrumentation of the xvm would be extremely useful tool for the research community. Those of us interested in virtualization are very interested in monitoring the behavior of these systems and with low engineering effort! I was hoping to get feedback on

I''ve tried using S10 U6 to reinstall the boot file (instead of U5) over jumpstart as its a ldom, noticed a another error. Boot device: /virtual-devices at 100/channel-devices at 200/network at 0 File and args: -s Requesting Internet Address for 0:14:4f:f9:84:f3 boot: cannot open kernel/sparcv9/unix Enter filename [kernel/sparcv9/unix]: Has anyone seen this error on U6 jumpstart or is

Hi, since hostid is stored in the label, "zpool import" failed if the hostid dind''t match. Under certain circonstances (ldom failover) it means you have to manually force the zpool import while booting. With more than 80 LDOMs on a single host it will be great if we could configure the machine back to the old behavior where it didn''t failed, maybe with a /etc/sytem

Suppose I have a storage server that runs ZFS, presumably providing file (NFS) and/or block (iSCSI, FC) services to other machines that are running Solaris. Some of the use will be for LDoms and zones[1], which would create zpools on top of zfs (fs or zvol). I have concerns about variable block sizes and the implications for performance. 1.

That is...is there a mechanism provided to do this? As an afterthought, this also applies to non-global zones, although one can stick something in the oem-banner eeprom variable that is identically visible on all the zones, which is not the case on LDOMs. However, that''s not a supported mechanism. Having something that was would be better. Ideal if the same mechanism (on what might or

Under Solaris 10 on a 4 core Sun Ultra 40 with 20GB RAM, I am setting up a Sun StorageTek 2540 with 12 300GB 15K RPM SAS drives and connected via load-shared 4Gbit FC links. This week I have tried many different configurations, using firmware managed RAID, ZFS managed RAID, and with the controller cache enabled or disabled. My objective is to obtain the best single-file write performance.

I have zfs on my base T5210 box installed with LDOMS (v.1.0.3). Every time I try to jumpstart my Guest machine, I get the following error. ERROR: One or more disks are found, but one of the following problems exists: - Hardware failure - The disk(s) available on this system cannot be used to install Solaris Software. They do not have a valid label. If you want to use the

Dear Community, I have been using two types of survival programs to analyse a data set. The first one is an R function called aftreg. The second one an STATA function called streg. Both of them include the same analyisis with a weibull distribution. Yet, results are very different. Shouldn't the results be the same? Kind regards, J -- View this message in context:

Hello, I am trying to update files on LDOM boot disk from Control Domain, but I can''t get it working fully. I have a setup that allows to quickly deploy LDOM guest domains. The Golden OS Image of guest domain boot disk is on a ZFS Volume. This ZFS Volume has been Snapshot and Cloned for the quick deployment of guest domains. Filesystem in both the control domain and guest domain is

Hi world, I have a 10-disk RAID-Z2 system with 4 GB of DDR2 RAM and a 3 GHz Core 2 Duo. It''s exporting ~280 filesystems over NFS to about half a dozen machines. Under some loads (in particular, any attempts to rsync between another machine and this one over SSH), the machine''s load average sometimes goes insane (27+), and it appears to all be in kernel-land (as nothing in

I''m setting up a two-node cluster with 1U x86 servers. It needs a small amount of shared storage, with two or four disks. I understand that the J4200 with SAS disks is approved for this use, although I haven''t seen this information in writing. Does anyone have experience with this sort of configuration? I have a few questions. I understand that the J4200 with SATA disks will

Hi all, We just got a shiny new T5440, and one of the first things I noticed (besides the insane number of hardware contexts), is that dtrace takes 30 seconds to a minute to fire up scripts with 5-6 probes, where our T5220 usually takes under a second. Shutdown is similar, though slightly faster. This is mostly annoying because it takes so long to attach that it''s hard to tell when

Hello Everyone, My question is simply what are my best options for successfully installing virtual tools on an Open Solaris OS running on Sparc Architecture. My hardware is a Sun Blade 2500. From what I have read Virtualbox and Xen do not work on Sparc technologies. What options do I have? Thank you in advance for any advice, Dan -- This message posted from opensolaris.org

I am running OpenSolaris build 134 on a T1000 (Sparc). It has been an uphill battle getting this far. Many of the commands I find in the various documentation won''t work for me. ------------------------------------------------------------ steve@t1000:~# pfexec pkg install xvm-gui Creating Plan pkg: ''xvm-gui'' matches multiple packages

Today I updated the firmware on my StorageTek 2540 to the latest recommended version and am seeing radically difference performance when testing with iozone than I did in February of 2008. I am using Solaris 10 U5 with all the latest patches. This is the performance achieved (on a 32GB file) in February last year: KB reclen write rewrite read reread 33554432

apparently if you don''t order a J4200 with drives, you just get filler sleds that won''t accept a hard drive. (had to look at a parts breakdown on sunsolve to figure this out -- the docs should simply make this clear.) it looks like the sled that will accept a drive is part #570-1182. anyone know how i could order 12 of these?

I am trying to simplify a text variable by matching and replacing it with a string in another vector so for example in colours <- paste(letters,colours(),"stuff",LETTERS) find and replace with ("red","blue","green","gray","yellow","other") - irrespective of case its a large dataset, so i'd like to be able to do this
