Under Solaris 10 u6 , No matter how I configured my ARECA 1261ML Raid card I got errors on all drives that result from SCSI timeout errors. yoda:~ # tail -f /var/adm/messages Jan 9 11:03:47 yoda.asc.edu scsi: [ID 107833 kern.notice] Requested Block: 239683776 Error Block: 239683776 Jan 9 11:03:47 yoda.asc.edu scsi: [ID 107833 kern.notice] Vendor: Seagate

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

Hi. I'm looking at deploying a freebsd 7-release server with some storage attached to an areca ARC-1680 controller. But this card is not mentioned in 'man 4 arcmsr' (http://www.freebsd.org/cgi/man.cgi?query=arcmsr&sektion=4&manpath=FreeBSD+7.0-RELEASE). Areaca's website does mention freebsd as a supported OS (http://www.areca.com.tw/products/pcietosas1680series.htm). Has

Two weeks ago I (clean-)installed CentOS 6.2 on a server which had been running 5.7. There is a 16 disk = ~11 TB data volume running on an Areca ARC-1280 raid card with LVM + xfs filesystem on it. The included arcmsr driver module is loaded. At first it seemed ok, but with in a few hours I started getting I/O error message on directory listings, and then a bit later when I did a vgdisplay

Hi, is the areca 1100 Raid Controller supported by CentOS 5? Or is there a kmod rpm available? Thanks Juergen

Well, I''ve searched my brains out and I can''t seem to find a reason for this. I''m getting bad to medium performance with my new test storage device. I''ve got 24 1.5T disks with 2 SSDs configured as a zil log device. I''m using the Areca raid controller, the driver being arcmsr. Quad core AMD with 16 gig of RAM OpenSolaris upgraded to snv_134. The zpool

CentOS 7.4 client mounting a CentOS 7.4 server filesystem over nfs4. nfs seems to be much slower since the upgrade to 7.4, so I thought it might be nice to mount the directory as v4.0 rather than the new default of v4.1 to see if it makes a difference. The release notes state, without an example: "You can retain the original behavior by specifying 0 as the minor version" nfs(5)

Is anyone running any Areca RAID controllers with the latest CentOS 7 kernel, 3.10.0-693.2.2.el7.x86_64? We recently updated (from 3.10.0-514.26.2.el7.x86_64), and we?ve started having lots of problems. To add to the confusion, there?s also a hardware problem (either with the controller or the backplane most likely) that we?re in the process of analyzing. Regardless, we have an ARC1883i, and

Hello, Sorry for the (very) long subject but I''ve pinpointed the problem to this exact situation. I know about the other threads related to hangs, but in my case there was no < zfs destroy > involved, nor any compression or deduplication. To make a long story short, when - a disk contains 2 partitions (p1=32GB, p2=1800 GB) and - p1 is used as part of a zfs mirror of rpool

As per my previous message, I've spent about 3 months trying to debug a problem that was causing all disk I/O to go very slowly. One of the things which made this nearly impossible to diagnose was the absolute lack of priority given to the console. Logging in on the console would take 12-15 minutes. Hitting enter on the console would usually take between 3 and 5 minutes. This

Hi listmembers, not a really urgent question, but i''m just curious about it: Is it advised to use an irqbalanced on dom0 when running domU''s pinned to particular cores? as an example, i''ve got a dual quadcore xen system running with domU pinned to cores 1-3 (CPU#0) domU pinned to cores 4-5 (CPU#1) domU pinned to cores 6-7 (CPU#1) so dom0 should have 100% time on

Hi, To follow up my CentOS 4.0/Areca SATA RAID driver disk I created a month or two ago, I have now created kernel-module-arcmsr RPMs containing just the kernel module to track the kernel updates. This means: a) No need to patch, rebuild and maintain customised kernels for Areca support b) Keep everything maintained with RPM I've taken the latest 1.20.00.07 kernel driver source as found in
