Hi everyone, I have a udev rule file that contains a singular rule: SUBSYSTEM=="block", ACTION=="add|change", ENV{ID_VENDOR}=="*Google*", ENV{DEVTYPE}=="disk", ATTR{queue/scheduler}:="noop" When I use a Google Cloud instance and boot it, things work as expected and /dev/sda (a persistent disk) uses the noop scheduler. If the instance also has a

The mtx binary requires my tape library to be assigned a sg# driver, but the kernel periodically renumbers the sg devices. Normally, we would write a udev rule to manually assign a persistent name, but it looks like things have changed as I can't seem to get a match on CEntOS7. I'd appreciate any feedback or pointers to help me get my rule working. My two attempts are below. cat

Hi Kalever! First of all, I really appreciate your test results for block-store(https://github.com/pkalever/iozone_results_gluster/tree/master/block-store) :-) My teammate and I tested block-store(glfs backstore with tcmu-runner) but we have met a problem of performance. We tested some cases with one server that has RDMA volume and one client that is connected to same RDMA network. two

Out of haste I decided for the first time not to pull down and compile iet to export a single volume to a windows machine so I just used tgtd. Well, much more time later than otherwise would be the case had I used iet, when I mount the volume on the windows ini, it can't find and install a driver? WTF? This have anything to do with the tgtd being a tech preview:) Anybody seen this b4? jlc

Hi, I was wondering if anyone has successfully configured two lsi/3ware 9750-4i series controllers for multipathing under CentOS 5.7 x86_64? I've tried some basic setups with both multibus and failover settings, and had repeatable filesystem corruption over a iscsi(tgtd) or nfs3 connection. Any ideas? Vahan

Hey everyone, Is anybody aware of a /true/ active/active multi-head and multi-target clustered iSCSI daemon? IE: Server 1: Hostname: host1.test.com IP Address: 10.0.0.1 Server 2: Hostname: host2.test.com IP Address: 10.0.0.2 Then they would utilize a CLVM disk between them, let's call that VG "disk" and then directly map each LUN (1,2,3,4,etc) to LV's named 1,2,3,4,... and

This idea is intruiging... Suppose one has a set of file servers called A, B, C, D, and so forth, all running CentOS 6.5 64-bit, all being interconnected with 10GbE. These file servers can be divided into identical pairs, so A is the same configuration (diks, processors, etc) as B, C the same as D, and so forth (because this is what I have; there are ten servers in all). Each file server has

Hi, I'm starting to experiment with iscsi based volumes and while this works fine so far I ran into a problem. When I add a LUN to a target and refresh tgtd all i/o to that target seems to hang for five seconds. This is obviously less than ideal if the plan is to use the target for lots of guests. There is also the possibility to create one target with one LUN for each guest disk but that

Hi all. While playing with iSCSI Enterprise Target + multipathd on CentOS 5.1 (both the target and the initiator/multipath/xen box are Cent 5.1), I encountered a strange fault condition that leads to a kernel panic in a version of Xen 3.2.1-rc2 pulled from a couple of days ago. My lab consists of two Clovertown machines with dual GigE into separate switches. The target box is softraid5

By natively, I take it using kernel /vmlinuz (vs kernel /xen) Not yet, but working on setting up such an environment. (At this time, I was using virt-install to reproduce the problem, and the original server we are testing on did not support kvm but the 2nd server does).

I just joined the list, and I see in the archives that about a month ago there was a brief discussion of SRP, but it was dismissed. I urge people to take a look at this site: http://srp.stanford.edu/srp/ It's very cool. Let's say I'm on vacation visiting a friend, and I want to log in to my account back home. I trust my friend's machine, but I don't have my home
