Thats what i am wondering. this morning, doing a heavy file IO since last night i got the dreaded
SR_BACKEND_FAILURE error 47 on one host, which used to happen a lot when i first started. I thought i had this one fixed after replacing a mobo and adding Ram to hosts.
Theonly way for this to happen is to manually change the amount within the XS cli correct?
Im still on 6.5 sp1 in production though.
I am certain the default is supposed to be 752MB on 6.x
@scottalanmiller oh right that is only for apc power chute.
Last i checked, UPS support in Xenserver 6.5 was having a physical Windows box with XenCenter installed and hooked to ups. that box would detect power loss and use xe commands to shutdown your guests and hosts. that is how i set it up here a few months ago.

Youll be even happier when Get Office reinstalls every time you do a windows Update. Then it pops up in notification area every single time you logon/reboot.
Kind of in the same boat here with the hybrid deployment. Last IT guy coudlnt figure out why the network and servers were becoming unavailable multiple times a day(dude worked here for 1.5 years, didnt do a thing as far as i can tell). So he decided to go O365 and Exchange Online. He paid the money for exchange online, got a hybrid deployment setup, then didnt work here anymore. Didnt migrate anybody to use Exchange Online.
I was then hired, i fixed all the local network issues.
Our Exchange online sub expires next week, really trying to decide whether to renew this sub or not. It is a few thousand dollars to renew. Just doesnt seem worth it since Exchange is locally running without issues.
xferring my ueb backup vdis to new ubuntu storage server. 60-70MB/sec from iostat, hitting nearly 1750 iops(not all the time tho) according to XenCenter. Still going to take all afternoon and most of the night.
Did DustinBs replacement drive work?
@BRRABill
I made a wordpress site, internal only, using Debian. works great.
oh, you dont mean what i said. oops
use ctrl-home to force bios update from a usb stick or floppy during post
You dont use server racks or virtualization?
You also missing the point about whether or not you have a rackmount case. Buy a new motherboard, still a better option that whatever you are thinking of doing. By the time you have found a solution to this, you could have a new board from newegg or amazon in your hands. hell, you could go to local mom n pop store and buy one in less than time than it takes to reply to this.
OR
make that big raid volume like you want, then put another disk or 2 in the leftover mobo ports(since yorue using a raid card for the big volume), and install windows on that disk. The data is what is important, not windows install. That can be replaced in minutes.
A newer motherboard with uefi would be cheaper than a newer rackmount case with backplane. cases like that worth buying cost $500.
You could make a big array, then when youre installing windows make a 350GB partition for the windows install, then use the rest as another disk(data i guess) for that server.
Are you able to see the errors and things while it is booting? Not trying to teach you linux, but if you hit F12 while Mint is booting it shows you all its messages, services starting, driver detection all that, instead of a useless(in this case at least) Mint logo.
as this is a laptop the uefi/bios options might be limited, but are you able to change the sata mode to/from ide/ahci? what about disabling or enabling legacy usb support? Not even sure those are options anymore in uefi.
Further note.
This seems to be a problem when using IET iscsi service. This IET seems to be an older implementation of iscsitargets on linux.
I removed IET, installed and configured targetcli, removed the lvm filter. All is much better now, and dmesg shows no errors on boot.
Also getting higher performance now as well with targetcli v iet
Pretty happy about that.
This is while moving a vm in xenserver to new storage.
