I have a raid 5 using mdadm in my home storage computer. Right now it's set up with 3x 500 gig drives as raid devices and a spare 500 is a hotswap. I've nearly filled the storage pool and would like to add in the hotwap drive to the storage pool. I read the man page but am unsure of what I do exactly. I've figured that I'd have to use mdadm with the grow command but am unsure of which drives to point to how in the proper syntax. Any help would be appreciated as I feel silly for not being able to figure it out. And to avoid any argument I have my data backed up elsewhere and I know raid isn't a form of backup etc. Here's the printout of: sudo mdadm --detail /dev/md0 code:

ShoulderDaemon posted:mdadm --grow --raid-devices 4 /dev/md0 That's it! I suck at understanding man pages. I'll give it a go and report back. Edit: raid looks good, it's flagged as "clean, rebuilding" in webmin and I hear the drives doing their magic. Now all I have to do is poke around and figure out how to get email notifications sent to me if bad things happen. Slow is Fast fucked around with this message at 21:24 on Mar 9, 2009 |

Here's something that's bugging me. I'm trying to raise the limit of open files on a Linux box (I'm running a distributed computing network on it, 1024 open files really isn't enough.) Since I'm going to have programs SSH'ing in and running other programs, it rather needs to be automatic. "ulimit -n" reports 1024, and that isn't enough, so I went about trying to change it. Added to /etc/security/limits.conf: code:code:I ran into something online which mentioned that there was an SSH bug such that "UsePrivilegeSeparation yes" in the file made it ignore the limits.conf file. I changed it to "no" and it's still 1024. There have been multiple reboots through all of this, so I don't have just stale servers running or anything  All of this is being done via SSH, since I can't really log in directly. Annoyingly, I have a VM with what I thought was the same setup, and it works just fine ("ulimit -n" gives 32768) - the only known difference is that it's Ubuntu 8.10 Desktop, and the new one is Ubuntu 8.10 Server. I'm out of ideas on how to even debug this one, I can't find any info on how to track where the ulimit is coming from. Suggestions?

My raid rebuilt itself and its showing the other drive as being added. The only problem I'm having is that my other computers aren't able to use the new space. Windows mapping the network drive still reports it as only being 1tb and not 1.5 like it should be with the new drive. I deleted the mount point and tried redoing it to see if that was the problem. I'm not sure where to go from here.

I'm using Ubuntu 8.10 and have an annoying mimetype issue. How can I get jpg and JPG to show up as the same? The system does not treat jpg and JPG's as the same file type. It has created an entry for JPG, but I was hoping to just add it as one of the extensions. The single entry does not have all the nautilus support etc that jpg does. My camera uses all upper case when saving pictures, and I haven't found a way to change that.

Does anybody know of a good live CD that supports NTFS read/write? I'm trying to save some files of a dieing NTFS drive by offloading them to a working NTFS drive. For dded fun, all I have to boot off of currently is a Ubuntu 7.10 Live CD with no hard drive (though with a 4GB USB stick and I can install a second DVD burner, but if I can get away with only one DVD drive that'd save me some work.)

Ubuntu 8.10 Live CDs use NTFS 3g. I'm not 100% positive, but I know I was doing read/write to my NTFS drive off one last week, and I'm fairly sure that's a tell-tale sign.

Even if ntfs 3g isn't on an Ubuntu livecd by default, you can install it via the package manager.

Awesome, Ubuntu 8.10 worked out-of-the-box perfectly! Score another one for Ubuntu, I guess. Now for an even better question: I need to run the Samsung hard drive diagnostic utility, esTool. Problem is, it only runs off a DOS boot disk. So how do I create a DOS boot disk from within Linux? I'd prefer to get it running off my USB stick, but I'll settle for burning an entire CD for a 2 MB utility, I guess. Samsung, as some sort of sick joke, provides two versions of esTool on their page, one for a floppy and one for a CD-ROM. The floppy version is just a zip containing estool.exe; the CD version, however, is zip file containing an ISO. Now, if you were expecting an ISO -- a file format meant to contain an exact replica of a disk -- to be able to be burned to a disk and you're good to go, oh ho ho, jokes on you: the ISO just contains estool.exe and a batch file called run.bat containing only the line "estool.exe"

I want to update Pylint to a newer version on my laptop running ubuntu hardy. But after adding the repo to synaptic, it doesn't pick up the more recent version. Does that mean hardy can't use anything past .13 or am I doing something wrong? I am using pylint with pydev and it does not handle with statements correctly, meaning modules using with lose all static checking and warnings.

musclecoder posted:Just making sure you did the basics, did you do a sudo apt-get update after you added the url? Yup. Normally I can figure stuff like this out, but I don't know what to look for. I've added the repo along with the signed key, I've done similar before and when I've done it wrong it complains very loudly. Nothing in ubuntu should be relying on pylint, so no dependencies should prevent me from using the newest version. And pylint 1.4 and above support python 2.5, so that shouldn't be an issue. I can't see what I'm missing.

What version of pylint do you need? It looks like it shouldn't be too hard for me to throw together a backport for you against hardy. Edit: If you have the hardy-updates apt source configured (which you should), then you should be able to install this .deb from jaunty which will bring you to version 0.15.2. If you need better than that, Debian has 0.16.0 which will probably install directly, but if not can be rather trivially repackaged for your version.

Silly question, why are you wanting to install it via Apt anyways? I've found the best/easiest/least painful way to manage Python modules is via easy_install or pip, so that only my core Python itself (and `python-setuptools` for easy_install) are in Apt and the rest I install via easy_install/pip. In terms of being able to upgrade, I think those tools are capable of upgrading; in terms of removal, they can't, but use of virtualenv makes it (and management of Python libs overall) a whole lot easier. (Note that all this doesn't imply that doing it via Apt is bad per se, but I've been a Debian sysadmin and Python coder for years, and wrestled with the problem of Python libs in/out of Apt for a long time. Switching to the above setup has been amazing in terms of keeping things straight for me.)

Another question! (Thanks for the prior help, issue solved) I'm trying to install rancid on this box, following the instructions from this guide: http://www.linuxhomenetworking.com/wiki/index.php/Quick_HOWTO_:_Ch1_:_Network_Backups_With_Rancid All was going well up until I got to the part where I'm supposed to run the rancid-cvs command. At first I got the error 'cvs: command not found' and quickly realised that I needed to install something else, so a quick 'yum install cvs' fixed that. However, now when I run the rancid-cvs command, nothing happens, no error, no output at all, certainly not the output shown in the guide there. I tried re-compiling/installing rancid from the beginning in case something got missed due to cvs not being present earlier, but same problem. Any idea on what I can do to try and diagnose the problem? I'm running Fedora 10. to make sure nothing was happening instead of it working, just no output, I checked to see if the /usr/local/rancid//var/CVS/networking/ directory was created, it wasn't.
