General :: Automate Reboot And Possible Pending E2fsck's?
Apr 19, 2010
I have a heavily used file server that I want to restart, then if it requires e2fsck's on any volume to run them after it restarts. The only problem is that the server is rarely rebooted, and they said it might kernel panic because its been so long. I've heard there's a way to have it go past the kernel panic if it does happen, but I'm not sure how to do that or the other stuff.If it was a Windows server, I would schedule a shutdown with the force switch, and have the chkdsk's already scheduled for each volume on reboot. But for RHEL, I really don't know.I'm hoping this can be done, so that way I can have it kick off at say 7am, then when I get in at 8am it will probably be near the end of the e2fsck's so I can see what's going on.

I know if I do a shutdown -rF now, it will perform an e2fsck on all my volumes with the -y switch. But if I just want to check one of the volumes rather than all of them, and have it use the -y switch so it will automatically answer yes to everything, how can I do that?I'm using RHEL, and have a huge volume I need to run a check on, and I dont want to sit there for the next 24 hours hitting the Y key every time it finds a problem ;-)

I have been forbidden to enable automatic updates on our Ubuntu servers, for both security and regular packages.When I log into any of my four Ubuntu servers, the welcome message contains this:
39 packages can be updated.
26 updates are security updates.
However, when I run the Nagios plugin that monitors APT, I get:
% /usr/lib/nagios/plugins/check_apt
APT WARNING: 33 packages available for upgrade (0 critical updates).
I need to know how to properly detect that there are pending security updates, and regular updates. Once I can do that, I plan to write a Nagios script that will return WARNING for pending regular updates, and CRITICAL for pending security updates.

I didn't realize my system drive had filled up... and TaskWarrior overwrote my 'pending.data' with a 0-byte copy. d-: I had worked SO hard to get all my tasks imported from various other notes (many of which I deleted along the way), and hadn't yet prepared for the possibility of data loss. Should've set it up to use my Dropbox...why doesn't TaskWarrior make ANY backup buy default? That data is so important, and yet so small and trivial to backup. Anyway, my 'undo.data' is totally intact and seems to contain all the information theoretically needed to reconstruct 'pending.data'. Unfortunately right now I have no sample 'pending.data' to look at. d-: OR: does anybody know of a simple Linux utility I can use to recover previous file versions? It's possible no data was overwritten, since the replacement is empty.

I have a volume on my server that according to tune2fs is "clean with errors", so i'm assuming I either need to unmount the volume and e2fsck it, or reboot and drop into maintenance mode and do itThere aren't any live samba shares off that volume, so i'm thinking I could do it without taking the server down, as this server is only for samba shares, which are on a different volume.Could someone tell me if I'm taking the right approach? I've never done unmounting and mounting before, but I've read it can be done manually without affecting how the volumes are mounted when a server starts. i'll have to look up the commands.

Other than when there are errors in the messages log or when you have file system problems, when should you e2fsck volumes? I have a lot of volumes that have 500GB to 1TB of data on them, and it takes quite a while to e2fsck them, so wondering if its something that should be done regularly, or only when there are actually problems.

Why does an e2fsck restart itself after a while, does it get to a certain number of errors than has to start over from the beginning? are there any tweaks or switches you can use to make it run more efficiently?

I have two volumes, both with 800GB total used on them. lets call them /vol1 and /vol2. /vol2 is just a cron'd rsync'd copy of a folder on /vol1 which is a live share for many users.If I temporarily suspend the cronjob doing the rsync's from /vol1 to /vol2, is it safe to unmount and e2fsck /vol2, then remount it somehow?
Both /vol1 and /vol2 say the filesystem state is not clean when i do a tune2fs -l on them both. According to tune2fs both will check themselves upon restart, but if I can do /vol2 since it isn't the live data beforehand, that will cut my downtime in half the next time i restart the server.But I also wonder that if I can do this, then i remount /vol2, will the "not clean"-ness of /vol1 just be rsync'd back over to /vol2 the next time the rsync runs?

If I umount both of them, can I run an e2fsck on each at the same time through 2 putty sessions, or will that not really gain me anything from doing them one after another?

I want to perform an e2fsck with the y switch (so I dont have to answer yes to every question) on two volumes on a server the next time I restart it. I don't want to do a shutdown -rF because 1) I dont want to check the other volumes and 2) it seems when I do that, the e2fsck doesn't keep restarting itself over and over to fix all the problems. Seems like it runs once, then if it fails it drops you to the repair console in single user mode. I'd rather just have it start the check that will keep repeating over and over right away, because I know it'll take more than one pass.

If I issue a shutdown -rF now, it will force e2fsck's on all the volumes when it reboots. But once the checks automatically finish, does it restart normally? I want to run e2fsck's on all my volumes, but dont want to stay the probably 5 hours it will run, so hoping someone knows for sure what happens.

I have a dell PE1750 server which would not boot up after a power failure. I am thrown to a shell for maintenance after showing an error in file system check. The server was running - Red Hat Enterprise Linux AS release 3 (Taroon). Please let me know if I can try to recover from this error by booting from the 1st CD of a higher version of linux like RHEL5. I ask this because I do not have the old media with which the system was setup. Can the use of latest OS CD cause any problem?

I currently have a setup which allows me to connect to all computers on my home network via SSH and RSA keys. I'm very security-conscious, so all of my keys are passphrase protected. I'd like to essentially set something up where I'm running Unison on a cron job to back up to a file server on my network, which we'll call timmy. I've noticed that the first time I try to use a key on my Ubuntu laptop teeks, I get a dialog which pops up asking me to type in my key passphrase. I've heard that for servers needing to make automated backups like this that one should use ssh-agent to ask for the key passphrase on login/server start. How can I set this up on teeks?
I'd essentially like to have the following happen:When I boot and come into the OS, prompt visually for the passphrase as is done when I first use a key.If I SSH into this computer (as it's internet-facing) and I haven't provided the SSH passphrase yet, then prompt for it. (Sometimes, I might need to remotely reboot the machine over SSH, so I'll be SSH'ing into it after it reboots and I'd like to be able to authenticate the key without having to VNC in and do it manually.)

I'd like to get the information about automatization of the tasks in Linux, more specifically in Fedora with minimal installation (without graphical interface and so on).The application (developed in C) needs to be started automatically when the computer is initialized. I've read about cron but I guess it's not a solution in this case because whenever computer starts the application must run once.I also have read about the/etc/ rc.local file but I made some tests changing it and they didn't work, the computer starts asking me the login and password but nothing run after that.The inittab was the same. In this way, someone know how to initialize an application developed in C when the computer starts?

I would like to automate a definition process. I have 11,581 to define. :|
I would like to read each word, copy the definition(s) and append it next or below the word or save definitions to file.
The word list has one word per line.
Python script?
Bash?
Perl?
Its an interesting project but I cant seem to figure it out. Lack of programming skills.

I need to ftp some files nightly from my linux box to an arbituary ftp server not controlled by me.
The ftp server admin has granted me an account for the purpose, but do not wish me to store the plain username or password in any script files for security reasons. How can I do that?
the wrong way would be:
Code:
$ cat my_script
open server_address
user plane_ftp_username plane_ftp_password
put a.txt
[Code].....

I've been using Windows Home Server as a Backup Appliance, Media Server and Share Server at home for some time. I decided it was costing me allot of juice so very early on added the "Lights Out" add-on to ensure it was only running as and when needed.
I'm now looking to switch to a Linux based server and I'm looking for a similar tool/set of tools for advanced power management.
Now the question;
Anyone got any all-in-one suggestions (i.e with client parts for both Windows and Linux and a server part for the Linux server), or can anyone simply verify that I'll need to set-up all the individual bits for this myself separately?

I've inherited the following Virtual Machine scenario and am new to Linux Administration and Patch Management. The Host Operating System is Windows 2003 Enterprise, which has VMware Server 2.0.2 installed. Under the VMware Server 2.0.2 I have a Ubuntu 32-bit OS web server running Apache2 Web Services. When I log onto the Ubuntu server (9.10 32-bit) I see the following two lines just above the new mail/last logon lines.
85 packages can be updated
55 updates are security updates
I would like to see at least a summary of each update and its urgency so I can notify the various developers/server owners to get their input regarding whether we should or should not apply that particular update to the server. We apply the patches in our test/dev environment first then once vetted there we roll them out to our production servers. What I am looking for is a way to automate the gathering of the information and once approval has been received automating the actual patching process so that I do not have to manually perform the apt-get process for each separate package needed/approved.
Ideally I would like a recommendation for a GUI based package to manage this process and that is capable of generating the appropriate reports for the 'powers that be' regarding the current security/patch management environment. For proof of concept I would like a free version that is not hamstrung in functionality but is not too costly to procure the production version with no limitations.

I'm not that familiar with sed and awk in order to be able to solve this problem on my own, so I'm calling on you for a bit of assistance. I'm writing a Nagios plugin to check our Oracle tablespaces and the output is given in one line like this: 1.04007771 TEMP 0 UNDOTBS1 .005340579 USERS 0 7 rows selected. I've been playing around with sed like below to delete the obsolete info and change every second space into a newline:
[code]...
how many tablespaces there are so I'd have to check all databases and 'hardcode' the tablespaces in my script. Is there any way to 'automate' this knowing that 'rows selected' preceded by a number is always the last line and using a sort of counter to auto-adjust the number to put in the -e 's/ / /2' part?

I have one of my Red Hat 5.4 box connected to the RHN and I managed to download and install selected files and updates. Lately, it has stopped doing so. I can go to the RHN webpage and select/apply the uppates I chose. But when I run the command "rhn_check", all I get is this
Loaded plugins: rhnplugin
[root@ELSDB09 ~]# rhn_check
Loaded plugins: rhnplugin
The updates are not installed and RHN shows that update as "Pending". I am not sure which log file I can dig into.
