Hi everyone, I'm attempting to get a test HA setup working where I have 5 systems, each exporting an iSCSI target to one another. Then, each server imports the exports from the others, creating a mesh. Now, I have zpool on one of the systems that I can activate on any of them in case one of the systems goes down. (This will be done manually to avoid any duplication of zpool imports across the set of systems.)
The one issue I'm running into is this: As soon as I get more than about 3 connections to one of the servers, it starts freezing up. It appears that the load goes way up, but I can't find out where from, since the system is so unresponsive, I pretty much have to reboot it to get it back to normal. Rebooting temporarily helps, but the system quickly goes unresponsive again. The same thing seems to happen on the client end as well. As soon as one of the systems imports about 3 or more of the targets, it becomes unresponsive and has to be rebooted. It eventually comes around if not rebooted, but becomes unresponsive on such a regular basis that its pretty much unuseable. My question is this: Is iSCSI a memory hog? Each of these systems has about 256mb to 512mb worth of memory, and work fine as a server otherwise. I know this isn't much per system, but their purpose isn't anything more than to serve out an iSCSI target, or act as an NFS server if its the master importing all the other targets. If iSCSI is a memory hog, is there any way to get it to reduce its memory usage, either by parameter settings or otherwise?
