I think that drive size might be related to something else.
General :: How Many "blocks Reserved For The Super User"
Jun 1, 2010When formatting an ext3 partition, the default -m option is 5 (5%). Two things I always wanted to know but were afraid to ask:
1) Isn't 5% way too much for the size of most hard disks nowadays?
2) Is that number or anything greater than 0 really necessary in ALL file systems? For example, is it necessary in a /home partition or any partition that contains no OS, just storage data?
General :: Script To Tar Up Files When A Partition Hits A Certain Use Percentage
Apr 19, 2011I am in need to create a script that queries how large a partition is and when it hits a certain percentage (say 90%) it will execute another script that tars up certain files (or they could just be part of the same script). I would create a cronjob that runs this script once a day.
I have the script that tars up the files I need, sets permissions, etc. (btw, the files in question are audit logs). I just need the part that runs something like a df -h and takes the use percentage of the /var partition in that query and if that percentage is greater than/ equal to 90%, it kicks off the tar script.
Here is a sniplet of the df -h with just the /var partition shown:

So, when the cronjob sees that the Use% is >= 90%, it would kick off the tar script...if not above 90%, it closes.
General :: Determine Number Of Blocks For A Partition?
Jul 1, 2010Can someone explain how to determine the number of blocks to determine the number of cylinders for a new partition on hard drive.
Why is block size divided by 1024?
I think I understand unit size is the total bytes per cylinder, I get that. I understand the anatomy of the hard drive (i.e. heads, sectors, cylinders.
My problem is, if I need to calculate the number of cylinders needed for let's say a 20G partition on a 120G drive.
Ubuntu :: How To Reduce Reserved Space For Root On Partition

By default it has 5% of the space (35GB!) reserved for root, which does not make sense for this partition. how can i reduce this percentage? there is already a lot of data on the partition and i'm afraid that mke2fs would erase all the data. is there a way to change the percentage without touching the data?

Nov 28, 2010My root partition is formatted as ext3 and I would like to perform a bad blocks scan on it. Normally e2fsck -c -c does this, but you can not run it on a mounted partition. I know it is possible to force a fsck to run at boot by creating the file /forcefsck but is it possible to specify that it should also check for bad blocks? If not, what is the recommended way to check for bad blocks on the root partition? I would like to avoid having to create a rescue disk and boot off of it.

Feb 11, 2011I have a 32-bit laptop running a dual boot with Windows 7 and Ubuntu 10.09 LTS.I've decided that Ubuntu just isn't for me, and I want to remove the partition and restore the extra hard drive space back to Windows 7.
Now, a few months ago, I accidentally deleted my Ubuntu partition through Windows Disk Management, and I ended up not being able to boot up my computer. I can't remember what the exact cause was, but I think it was a problem with the GRUB, and I think I fixed it by reinstalling Ubuntu. Does anyone know how I can safely remove the Ubuntu partition without having to go through all this again?

View 5 Replies View RelatedUbuntu :: Safely Resize A Partition Like Adding The Extra Space Without Touching The Existing Data?
Jul 9, 2011I have a BIG extended partition. It's at about 750Gb. Aside from that, I have 2 unallocated spaces, one at 240Gb and one at 5Gb. I want to make one of my storage drives bigger, and so that I can take advantage of all the space I have. (Those 250Gb have been unused for ages. I want to use them for my growing libraries.) So I wonder: would it be safe to put these smaller "chunks" into the extended partition, and still have a working systen? I don't want to mess it all up.
Also, can I safely resize a partition, like adding the extra space, without touching the existing data? I'm not exactly sure how the resize/move function in GParted works. Will it wipe and extend or only extend it by adding it? It would be nice to have these questions answered. Also, if it's to any help, this is my partition table as of now:
[Code]....
As for the first entries, they're unallocated. They're the primary drives, but they don't exist. I'm actually considering to move my partitions out of the extended one, because I only have 3 partitions that I use and will ever use. But if the extended partition is not a problem, I will just keep it this way.
I'd imagine that I first extend the extended partition to consume the unallocated space, and then I move it all to the end of the partition, and then resize sda7 to consume it, and get a 750Gb partition. Can this be done without loss of data?

Oct 1, 2010I'm working on a ~1 TB disk that was loaded with all kinds of images and documents that lost it's HFS+ partition table. The person for which I'm doing the favor of running scalpel says it's likely there's 90GB of stuff. Somehow, the disk got relabeled/MBR changed to some FAT variant that works on the whole Terrabyte.
Attempts to recover the partition info failed.My first try with scalpel finds more than 90GB of image file headers alone and that blows through all of my storage. Of the headers found and recovered as images, a simple test shows most of the image files are broken. The cluster size option does not work if I use it by itself. It errors out before it gets going.I want to speed things up and skip the countless broken image files.

General :: View Bad Blocks On Mounted Ext3 Filesystem?
Mar 18, 2011I've ran fsck -c on the (unmounted) partition in question a while ago. The process was unattended and results were not stored anywhere (except badblock inode). Now I'd like to get badblock information to know if there are any problems with the harddrive. Unfortunately, partition is used in the production system and can't be unmounted.
I see two ways to get what I want: Run badblocks in read-only mode. This will probably take a lot of time and cause unnecessary bruden on the system. Somehow extract information about badblocks from the filesystem iteself. How can I view known badblocks registered in mounted filesystem?
General :: Filesystem Corruption Possibly Caused By Bad Blocks
Nov 5, 2010I'm trying to RMA a month old SSD, and they're giving me a hassle about it. The drive currently seems to work just fine, but I'm 95% sure that a few blocks went bad and corrupted some data about a week ago. I was able to mostly recover the data and correct for the bad blocks, but I don't really trust the drive anymore.
I'm running an up to date Debian Squeeze install with ext4 on this drive. My system started doing some bizarre things, to the point that it was unusable, so I rebooted it. As it was booting up, it complained about needing an fsck, which found dozens of non-trivial errors that it was mostly able to fix. It then proceeded to boot normally, except the drive mounted itself as read only (due to errors). Another fsck turned up a similar number of problems. This happened a couple of times before I ran fsck with '-c', which is supposed to scan for and work around bad blocks. That seemed to fix the problem, it hasn't given any more problems since then.
The manufacturer is refusing to RMA the drive unless it's completely unmountable right now this minute, saying that it was a one time problem that could have been caused by anything. Am I right in thinking that the problem has to have been with the drive if 'fsck -c' fixed it, or could something else be going on? If it was the drive, am I somehow being unreasonable in asking for a new one while the current one is "working"?
General :: Implications Of Bad Blocks When Reinstalling A Disk Image
Mar 17, 2010Let's say I'm using one of those PCs that uses a SSD flash drive in place of a more regular HDD.
Say I burn my favorite .iso distro and install it on this PC. I install my favorite applications and seek out and install any missing drivers and generally tweak the system like you do. When I am finally happy with it, I make an image of this installation to an external USB drive.
Now, say 9 months later some of those SSD blocks have gone bad because they were erased too often. They're no longer usable. Also, because I'm a sloppy person who can't be bothered to delete redundant stuff and run make-cleans and so forth, the disk is getting pretty cluttered and takes longer and longer to do stuff.
I decide the obvious solution is to remove and save any data I need to keep, then just over-write the disk with the image I made 9 months earlier.
The question is: will the firmware be smart enough to re-map my incoming image to avoid these bad blocks on the SSD? Or am I going to wind up with some parts of the image being located on bad areas of the SSD?
