comment RAID-5: Two disks failed simultaneously?
@Wardy, wouldn't raid 6 give you that?

I don't see the write penalty- random writes are cached, and sequential ones don't suffer as greatly from it.

comment Send interactive zoning commands to Brocade switch
Thanks :) I'm considering that program option, but it's a shame that Brocade makes this so hard.

comment Send interactive zoning commands to Brocade switch
I don't have screen installed on AIX... but reading about it, it certainly seems like something worth fighting to get. In the meantime, though, is there anything in the world of sessions, pipes, and redirection that can get me where I need to be?

comment Why would Linux VM in vSphere ESXi 5.5 show dramatically increased disk i/o latency?
I'm not sure, to be honest. I normally deal with it at a storage controller level, but this is on an internal disk.

You're welcome :)

comment Why would Linux VM in vSphere ESXi 5.5 show dramatically increased disk i/o latency?
Is there any chance this is due to ESX disk caching? Is the disk you're testing optimized for performance or safety? Also, if it's optimized for performance, can you look at the ESX cache utilization while you're testing? This write IO change in throughput looks like writes hitting a cache, and then slowing to the destage speed when it fills up.

comment Computers in-scope for PCI DSS
I agree that while this is a well written question that presumably has a good answer, this isn't the place for it.

comment Phalcon does not load under nginx and php5-fpm
Stefan, if this is what ended up helping you, could you answer your question and accept it? That way future visitors with the same issue will see the answer more obviously :)

comment Where is $BASH_ENV usually set?
I just finished reinitializing SSH and my non-interactive SSH commands are now working! Thank you so much for your help, I'd have never found that field on my own.

comment In Linux, how can I automatically assign an IPv6 address to an interface based upon its IPv4 address at boot time?
This is an excellent idea, in my uneducated opinion. My biggest reason for waiting for other people to push me into ipv6 is that I can't fit a whole address in my memory.

comment Where is $BASH_ENV usually set?
Yeah, that was the frustrating part- everything I need is set in .bashrc, which was just not being run :) Thanks so much for your help- I'm scheduling a change to reinitialize SSH and I'll report back. I assume it'll work.

Oh, I think I need to reinitialize ssh? /etc/init.d/sshd?

comment Where is $BASH_ENV usually set?
I found a difference! PermitUserEnvironment yes is set in /etc/ssh/sshd_config on the working server, but not the problem one. I changed it, but I just tested a command and it didn't work again. Does this file get parsed every time I try to ssh in? I don't have a ~/.ssh/rc for the user I'm working on, and there's no /etc/ssh/sshrc file on either system.

comment Where is $BASH_ENV usually set?
/etc/bashrc is identical, /etc/security/pam_env is the same, all the files in /etc/profile.d/ are identical, and the files in /etc/pam.d/ are almost identical, but there's no reference in the one file with slightly differently ordered lines that references $BASH_ENV.

comment Where is $BASH_ENV usually set?
they're identical and both contain if [ -f ~/.bashrc ]; then . ~/.bashrc; fi

Not identical, but the user I'm sending commands as has the same line in /etc/passwd on both systems.

comment How can I safely use storage thin provisioning?
We charge people for what they see, and since they get no discount for not using it all, we understand that they have no incentive to stay thin, other than it being the right thing to do. Since we charge people for what they see and hide the risk from them, all the money we save is on the "back end" IT budget.

That's a whole other kettle of fish :)
