Re: [OpenIndiana-discuss] Only one SSD detected on expander

so what was the cure? I looked at that link but didn't see an easily recognizable fix I have had this forever. Not a big deal but makes me nervous if I think my server is down.

[OpenIndiana-discuss] Smart OS Zones under OpenIndiana

[OpenIndiana-discuss] 151a7 ??
FWIW I just did an install of 148 (CD on hand) on a spare system followed by an update via the website. I was expecting 151a5 based on the website and named my BE accordingly. However, on rebooting, I see that I actually installed 151a7. Other than that, nice job.

Re: [OpenIndiana-discuss] Only one SSD detected on expander
I'm pretty sure I tried that, but now I can't be sure. I've already returned the drives and ordered the 840 Pros, which are supposed to have WWNs. If it turns out they don't, I'll give this a try before I return them, too. :-/ Thanks! -Scott On Oct 21, 2012, at 7:04 AM, carl brunning ca...@cblinux.co.uk wrote: Not sure if this help you But i had this problem on nexenta and the fix was the following in the /kernel/drv/mpt_sas.conf i unrem the line with mpxio-disable=yes; then reboot the system this fixed it for me and then i could see all my ssd when before only one show in the gui list this was for Samsung disk as well hope it is the same problem for you thanks CArl -Original Message- From: Robin Axelsson [mailto:gu99r...@student.chalmers.se] Sent: 21 October 2012 12:03 To: openindiana-discuss@openindiana.org Subject: Re: [OpenIndiana-discuss] Only one SSD detected on expander The worst case would be if the firmware image is signed and encrypted, which I doubt.

You can have the same kind of problems with any Illumos-based distribution if you activate a zone and let the machine just sit there for a week or so or have a lot filesystem activity using mmap(). Either way the machines will choke themselves to memory starvation. The only workaround we found are regular reboots (every 24h), or limit the ZFS ARC to an absolute minimum. I don't think you understand. My proxy tier does almost no reads from the file system. There is no content on the server. OK, sorry then. Same symptoms, different cause, albeit it's so bad that it makes the OS virtually unusable for any serious work. Ced This whole discussion sounds bizarre to me. I have a Solaris 10 Update 1 system with over a dozen zones with UFS with 8 Gig RAM and don't experience these types of issues. We reboot once a year, whether we need to or not. This is my limited understanding... - UFS basically consumes all unused memory for paging, without ever telling the OS, but releases it to OS processes when memory is needed. UFS does not tell the OS that it is using the unused memory as buffer cache, so you never know it when you check for your memory usage. - ZFS basically consumes all unused memory for ARC, but tells the OS when it is taking RAM. The ZFS ARC is supposed to give back memory when there is pressure to do so. You always know how much memory is really being used when you check your memory usage. I had issues in the past where disk I/O started to go through the roof, on UFS filesystems, when the free memory was getting below 4 Gig of RAM... a sure sign the apps were starving the invisible UFS buffer cache. I don't really understand how applications can be starved by ZFS unless ZFS can not give back the buffers (lots of constant full-table scans?) Has Illumos developers really confirmed such a ZFS bug, where it is not returning memory to the OS? This just does not sound right, to me.
