SysAdmin1138 Expounds: Moving /tmp to a tmpfs

posted on April 01, 2012 by SysAdmin1138

There is a move afoot in Linux-land to make /tmp a tmpfs file-system. For those of you who don't know what that is, tmpfs is in essence a ramdisk. OpenSUSE is considering the ramifications of this possible move. There are...

@Iain I had just finished a nice long answer to that shift staffing question then you closed it before I could submit it :-(

Iain

@RobMoir sorry - I can reopen it if you want. Just seemed like the epitome of NC to me

Q: New reputation factor: No questions penalty

Our site suffers from too many bad questions. We are the second worst site in the entire network regarding answer rate. Bad questions do not get answers and they drive away the most important community members: experts. We need more good questions. Good questions are asked by people who know what...

Rob Moir

@Iain I had a good answer, at least I thought so, and I think so does sysadmin. Its a slightly ropey question but its salvageable.

that's a pretty good april fool

Iain

@RobMoir Like I said I can reopen it. I agree that sysadmin1138's answer is good too but equally it doesn't answer the question asked, rather is discusses why the answer can't be answered

Rob Moir

I have a method of working out staffing I can post

its limited of course, its a real "how long is a piece of string" question, of course it is

12 hours of data recovery for me...

Similar to this question...

A: Recover NTFS data from a ZFS pool that was exposed as an iSCSI target

I've had this problem before and just ran into it again. I use the UFS Explorer tool as a last-attempt data recovery solution for deleted volumes. In today's case, I'm recovering data from an Linux XFS partition created on top of a ZFS iSCSI export shared via a NexentaStor VM sitting in a VMWare ...

I'd recommend that every admin have a copy of UFS Explorer handy - ufsexplorer.com

XFS failure? or just someone who deleted something?

ewwhite

I've never had an unrecoverable XFS failure...

it was actually a PROGRAM that was generating a ROLLOUT to a command line...

COPYSYS.DELETE LROUTINE
        CALL SCRNSAVE
        ROLLOUT ("rm -rfv /ppro/ppro" + SYSTEM)

        CALL GET.COP WITH SYSTEM
        IF (CHOP COPSMNT != "/ppro")
                ROLLOUT ("rm -rfv " + COPSMNT + "/ppro" + SYSTEM)
        ENDIF

        CALL SCRNREST
        RETURN
        ENDROUTINE

And that program had whitespace in a variable... that evaluated to something awful like...

rm -fr /directory/subdirectory/ *

so it was a clean rm -fr of 500GB of data

(not my fault)

MacClesfield. Sounds like the name of a detective. Mac Clesfield

Also.. is this the first time a guy's openly admitted to running a porn site? serverfault.com/questions/375727/…

Jeff Ferland

@TomOConnor Heh. Makes "massive loads" funnier.

Tom O'Connor

@JeffFerland I just refered to Coppermine gallery being a whore.

I'm loving this >10k reputation thing. I'm currently aiming to overtake my old boss :)

Lucas Kauffman

@TomOConnor I feel bad for him on one side, then again his running Joomla he's had it coming anyways

Tom O'Connor

@LucasKauffman DB and Apache on the same server => Bad News.

Jeff Ferland

7:37 PM

@TomOConnor Uh, what was your basis for the MySQL numbers?

Tom O'Connor

he posted his my.cnf

i dropped it into omh.cc/mycnf

Jeff Ferland

@TomOConnor 33.6GB of memory for 300 MySQL connections is wrong. Worst-casing every session variable can't be right.

Tom O'Connor

@JeffFerland It's plausible.

Lucas Kauffman

It's joomla

all high load problems are caused by shitloads of queries

Jeff Ferland

I'd say he needs a consultant to look at the server stats and actually tell what's going on, but since he's a month behind on the mortgage that's not happening

Tom O'Connor

7:42 PM

@JeffFerland I think he's a driveby.

Jeff Ferland

@TomOConnor I'm not going to sweat it... but I will say... "throw a 36GB db server at it" isn't the right thing either...

Tom O'Connor

I wonder how much SSL traffic he's serving.

@JeffFerland I didn't say that.

Lucas Kauffman

@TomOConnor secure porn :p?

Jeff Ferland

@TomOConnor Well, without context of chat it reads that way to me.
