The asker specified that they're using du :)

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.

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 :)

We decided that it was fine to pass on the savings from going thin equally to all storage clients. We bill per addressed TB.

We don't tell the clients anything about this, but we certainly lower the threshold that would cause us to add disk when we're at a higher provisioned capacity.

comment How can I measure complex I/O activity to develop realistic benchmarking?
+1 for replaying traces. That's how we benchmark high intensity oracle work on multi-tier pools.

In my shop, oversubscription isn't visible to the data owners unless they ask for it. We make it a storage decision, but promise to never bust a pool.

comment Hard and soft zoning vs. port and WWN zoning
Not related to the answer, but port zoning is the best practice for FICON fabrics

So you would recommend XGIG for mirror ports?

comment What limits a Device not to detect multiple LUNs behind a single target?
This question is overly broad, but I sense that you are having a problem detecting more than one LUN on a system you expect to be able to see more. If that's the case, please edit your question to provide more details about the problem. As it is, there is nothing preventing multiple LUN detection except a problem of some sort.

comment Can NetApp Snapshots be used as Backups?
You want to have some fun? Try doing snapshots on a snapmirrored volume for flexclones of the target. Then try using 100% of the non-reserve space on the source. It works until the snapshot backing that flexclone gets deleted on the source volume, at which point replication stops.
