General :: Check JFS Disks (fsck.jfs) At Every Boots Using Tune2fs Like Tool?

May 15, 2010

Fstab has at the end some values: 0 1 for / or 0 2 for /home or others.

It is nice to set tune2fs -c 2 for disks that have to be reliable and increase the security of the data.

tune2fs is not working for JFS. How to make this check at every single boot of the Debian/ubuntu machine?

General :: Hard Drive - Does Check Disks During Boot Instead Of Shutdown?

Dec 3, 2010

I'm just curious - why do all linux distros (all I've seen) run their periodic disk checks during boot? I mean, I understand that a disk should be checked now and then, but why does the system do it during boot, when I'm waiting for it to load, instead of checking them during shutdown, when (most probably) user doesn't need the computer anymore.

there is a tool, which can check and compare DNS records for me. I'd like to tell it to look at our private subnet, and it for to return records which have missing or different DNS records, than were expected. if it just looked up every record and returned it in a "neat" way, that'd work too.

Ubuntu :: Using Fsck To Check Windows Partition?

Mar 21, 2010

My windows partition isn't starting up, gives an error and suggests using chkdsk. However, I cant even reach safe mode or command prompt. I can still access my Windows hard drive through Ubuntu.I am wondering I can use a Linux tool to perform a check on this Windows partition? I found the fsck command, but I am confused about the warning about running it on a mounted system and about what exactly is a mounted system.

Can someone please tell me how exactly I wod go about doing a check on this partition? Its currently located in /media/disk.I can right click on the partition and unmount it. But if I do this, will Ubuntu still be able to see this partition?What command do I use to do fsck only on this Windows partition (and not the whole system and other mounted places)? How do I remount the Windows partition so that I can atleast salvage my data easily in case doing a disk check does not help?

Ubuntu :: Command Prompt And Said The 'file System Check Failed' And To Run Fsck Manually?

Feb 25, 2010

I have Ubuntu 9.10 installed on my HP desktop, but I'm running an older version (8.10) on a live CD so I can at least get online to ask for some When I tried to log on earlier it went to a command prompt and said the 'file system check failed' and to run fsck manually. I entered 'sudo fsck' at the prompt and I selected "y" to fix all the bad inodes, when it was complete it told me to restart, I then entered 'sudo restart' at the prompt and it said 'sudo uuid unknown'. I have not installed anything recently and I'm not sure what to do.

General :: Tune2fs Says Couldn't Find Valid Filesystem Superblock

May 12, 2010

I'm logged into a server through the CLI and did a df -T and confirmed all my volumes are ext3. but when I do a tune2fs -l /dev/sde it tells me

tune2fs 1.39 (29-May-2006)

Couldn't find valid filesystem superblock.

I don't have root access on the server, but is that why it's complaining, or is my syntax incorrect?

Debian :: Aborting "Check Forced" Of Disks?

Jun 9, 2010

Once a while, during boot, Debian forces checking of hard disks. I understand that's a wise thing to do. However, I wonder what you could do to abort such process and postpone it to next boot (let's suppose you are in a hurry and you have switched on your computer only for a quick glimpse to a document).

Ubuntu :: Tune2fs Not Working For 2TB HDD?

Oct 18, 2010

I have a Western Digital 2TB HDD on Ubuntu 9.10. This is my secondary HDD which is used only for Storage of media files. I mount it as & when needed only to stream my media content. I have tried many times to use tune2fs to free up the extra space which has been reserved automatically by linux yet although it accepts the commands & doesnt give back any errors, when I run the df- h or du- h commands, linux has still reserved 200GB & I only have 1.8TB to use. This extremely annoying as Im quickly filling it up with about 400GB currently available for me, that could easily be 500GB.

My primary drive is a seperate HDD of 320GB Storage is /dev/sdb1 for which I mount it to a folder called 'media-centre'. Then after mounting, I run the command: tune2fs -m 0 /dev/sdb1 media-centre I takes the command with no problems, I run df -h, & no joy. I have read my books at home as well as google searches & forums. Am I missing something simple here, does this command work only with certain types of HDD's?

I posted on another forum & followed a post that said I should convert from ext3 to ext2 as the journal is the cause, I ran a tune2fs -O ^has_journal etx2 /dev/sdb1 (something like that) & checked /etc/fstab which did not reference my storage HDD.

Fedora :: Cold Boots Often Take Up To 10 Attempts Before The Computer Successfully Boots?

Oct 29, 2010

my desktop pc is acting very strange. cold boots often take up to 10 attempts before the computer successfully boots. after the 1st successful boot, i can expect 1-3 "glitches". here's what happens:

the first few cold boots fail at various points during the boot process. there appears to be no pattern to it. when it happens, the machine is completely locked up. it responds to nothing, except holding in the power switch for 5 seconds. i'll go through this procedure several times.

finally, it will boot all the way to a desktop. from there, once i log it, i can expect it to lock up completely, usually once or twice. and then, finally, the screen will go blank and it will suddenly be back at the login screen.

usually, once i log in that last time, it's at least usable, although hardly stable. watching flash video seems to cause a complete lockup, with the sound looping. it doesn't matter where the content is coming from (videos or similar) nor does it matter which browser i'm using (firefox or chrome). i've stopped visiting videos-type sites in the meantime.

this installation has always been a tad bit screwy. 99% of the time, firefox fails to shut down properly, resulting in a message letting me know that a crash was detected. earlier today, i was alerted to 3 kernel crashes simultaneously.

right now, i'm using the pc, as normal. the random nature of the problems would lead me to believe it was hardware-related, specifically something like memory (ram). however, i installed memtest86+ and ran it. i walked away for 4+ hours. came back, it was running, no errors were found. i stopped the test and booted, trouble-free.

the pc seems to be stable enough for a backup, but this does have me concerned...obviously. i'm debating wiping the drive clean and installing f13, just as a test. if it's screwy as well, it would have to be hardware-related, wouldn't you think??

Debian Hardware :: Servers Which Contain SATA Disks And SAS Disks?

Feb 25, 2010

I have servers which contain SATA disks and SAS disks. I was testing the speed of writing on these servers and I recognized that SAS 10.000 disks much more slowly than the SATA 7200. What do you think about this slowness? What are the reasons of this slowness?

I am giving the below rates (values) which I took from my test (from my comparisons between SAS 10.000 and SATA 7200);

dd if=/dev/zero of=bigfile.txt bs=1024 count=1000000 when this comment was run in SAS disk server, I took this output(10.000 rpm)

(a new server,2 CPU 8 core and 8 gb ram)

1000000+0 records in
1000000+0 records out
1024000000 bytes (1.0 GB) copied, 12.9662 s, 79.0 MB/s (I have not used this server yet) (hw raid1)

Ubuntu Installation :: Which Disks Can Be Main Boot Disks

Mar 31, 2010

I have/had a PC with several hard drives, and a mix of ubuntu and windows on multi boot.The old boot drive died screaming, and I need to start again. (But my data is safe! yay!)

Is there anything special about which drive can be the main drive to start booting from? Or to put it another way, can I install to any of the other 3 and expect it to work, or do I need to switch them around so a different drive is on the connections for the recently dead one?

Ubuntu :: /etc/mtab And /proc/mounts Do Not Show Tune2fs Mount Option

May 23, 2011

I just discovered that you can automount an ext4 filesystem with acl enabled by running "tune2fs -o acl". (I knew about tune2fs but did not dare to use it until now). However, the acl mount option does not show up in /etc/mtab and /proc/mounts. Can I ignore this, or is there a way of telling the system about the actual mount options?

Edit: I can do "tune2fs -l <device> | grep acl | awk '{print $4}'" and if that isn't empty I can update /etc/mtab with "mount -f -o remount,acl <device>", but like the udev rule I previously messed with this seems lumberingly unelegant to me.
