Ubuntu :: List Directories By Number Of Inodes Used?
Mar 21, 2010I recently used up all my free inodes on my server. I had a bunch of mail messages that were sitting there using up a bunch, so I cleared the postfix queue. That gave me some room. What I'd like to do, is get a listing of the directories using the most inodes (or containing the most number of files), so that I can find the other culprits.Basically I want the output of "df -i" but to be able to do it recursively on a specific directory.

Each time the inode number is different. I made SMART tests on the disk, and all went fine. Do I have to worry? Could it be something related to a wrong shutdown? Update: I have just ran an fsck at boot, but when I logged in, the same orphan_cleanup was in dmesg.
Fedora :: F13: Increase The Number Of Loop Device
Sep 17, 2010In previous Fedora, we may add the following line to /etc/modprobe.conf
options loop max_loop=64

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.

Mar 14, 2011I'm trying to create an extended partition. In GParted, I shrunk the size of the existing partition and now want to create a new EXTENDED partition in the free, unallocated space. GParted only lets me create a PRIMARY partition. What am I doing wrong here?
Here's what I've got right now:
You can actually ignore the flag for the swap as "boot." That was me just messing around trying to get it to work. I've removed that flag. Not sure how the question of boot affects all of this...maybe it factors in somehow.
General :: Creating New Partition And Label ?
Mar 11, 2010I am a newbie to Linux and I am using CentOs. I am trying to create a new partion on my CentOs VM. I create a new primary partition using fdisk (I use the command fdisk /dev/hda). After I create the partition and use partprobe to write the partition to disk, I try to give the new partition a label. So, I use the command e2label /dev/hda LABEL=test
However, when I enter the command e2label /dev/hda3 , it doesn't display the label for the newly created partition. Am I doing something wrong here? Is the syntax of the e2label command wrong when creating the label for the new partition? Did I miss a step after writing the new partition to disk.

Jan 18, 2010My server started acting flaky this weekend and my Webmin interface was throwing strange errors. I finally tracked it down to the fact that I was out of inodes on my primary partition. I'm fairly certain that the /tmp folder has an outrageous number of files in it.I can't do an ls on the directory because the console just sits there forever after I issue the command. I also tried to do an rm -rf on the /tmp directory and it did the same thing.
View 14 Replies View RelatedGeneral :: Creating Extended Partition - RHEL 5.4
Apr 18, 2010I'm following the book RHCE book (5th edition) by Michael Jang. On the exercise on pg.140, creating partitions, I've created /boot (hda1), swap (hda2) and / (hda3). So far so good.
Next, I'm supposed to make an extended partition, containing the rest of the disk. So this should be hda4, right? But when I try to create either an LVM, or RAID partition, it creates hda4 AND hda5 under hda4. Why is that? Am I doing something wrong? The book next asks me to create /var as hda5, so if hda5 is already created automatically above, how am I supposed to create /var?
General :: Make System Partition Letter / Number Designations Persistent?
Aug 15, 2010Everyone who deals with Linux knows that partitions on hard drives are designated as "sdx#", i.e., sda1 sdb2, etc. I know through experimentation that the number portion of the designation is assigned not according to order on the disk, but chronologically in the order they are created.
Further, if you have several partitions on the disk-say, sda1 through sda3-and you delete sda2, the designation of sda1 will remain the same, but sda3 will become the new sda2. The creation of any further partitions on the drive will start with designation sda3 and increment from that point.
At times this creates a conundrum, especially concerning bootable partitions. Some time back I rendered a partition containing OpenSUSE unbootable because of this, even though Ubuntu owned the GRUB bootloader in the MBR. Ubuntu's GRUB could find and point to the partition using the command "sudo update-grub", but when OpenSUSE took over the boot-up process, its GRUB was pointed to the wrong partition and would freeze up.
My question is this:
Under Windows, one is able to make a Drive letter persistent. Windows will keep the drive letter for that partition and assign around it. Is there a way to change a drive designation number, or at least make it persistent, under Linux? It would be a handy method to forestall these types of booting problems, among other things.
Presently, when a person has installed Linux side-by-side with Windows and want to delete the Windows partition and expand the Linux partition into the free space, I will tell them to format the partition, then shrink it to next to nothing instead of deleting it. This preserves the partition ID scheme while giving them the space to expand their Linux partition into...especially helpful with a seasoned Linux installation that would be a PITA to reinstall and set back up.
Oh, and I already know about UUID. This article explains it, but if you look down through the comments, you will see reasons that it is problematic for desktop application and usage. I want to make it as simple as possible for new Linux users (and myself! ).
General :: Creating A RAID1 Partition With Mdadm On Ubuntu?
Jan 28, 2010I'm trying to set up a RAID1 partition on my Ubuntu 9.10 workstation.On this dual-boot system, Ubuntu is running from a separate drive (/dev/sdc - an SSD that is quite small, which is why I need more disk space). Besides that, there are two traditional 500 GB hard drives, which have Windows 7 installed (I want to keep the Windows installation intact), and about half of the space unallocated. This space is where I want to set up a single, large RAID1 partition for Linux.
(This, to my understanding, would be software RAID, whereas the Windows partitions are on hardware RAID - I hope this isn't a problem... Edit: See Peter's comment. I guess this shouldn't be a problem since I see both drives separately on Linux.)On both disks, /dev/sda and /dev/sdb, I created, using fdisk, identical new partitions of type "Linux raid autodetect" to fill up the unallocated space.
Device Boot Start End Blocks Id System
/dev/sda1 1 10 80293+ de Dell Utility
/dev/sda2 * 11 106 768000 7 HPFS/NTFS
[code]....
But so is "Device or resource busy" when trying to create the RAID array. Quite strange.
Update: Could the device mapper have something to do with this? How do /dev/mapper and dmraid relate to all this mdadm stuff anyway? Both provide software RAID, but.. differently? Sorry for my ignorance here. Under /dev/mapper/ there are some device files that, I think, somehow match the 3 Windows RAID partitions (sd{a,b}1 through sd{a,b}3). I don't know why there are four of these arrays though.

General :: Boot Windows Partition On Startup Or Creating A New MBR ?
Aug 2, 2010I have two hard drives in my desktop. One HD has a working Ubuntu system-hence the ability to post here- and the other contains Windows XP Pro. When the XP drive crashed I was able to re-install an image I had saved using Acronis. Unfortunately the dual-boot option at startup is no longer available. I can only boot to Ubuntu. Not so bad really but there are some programs on Windows that I need to use. Is there any way, using Grub perhaps, that I can reconfigure an MBR to include the second hard drive and the Windows system?
View 1 Replies View RelatedGeneral :: Filesystem With Inodes Close On The Disk?
Jan 9, 2011I'd like to make the ls -laR /media/myfs on Linux as fast as possible. I'll have 1 million files on the filesystem, 2TB of total file size, and some directories containing as much as 10000 files. Which filesystem should I use and how should I configure it?As far as I understand, the reason why ls -laR is slow because it has to stat(2) each inode (i.e. 1 million stat(2)s), and since inodes are distributed randomly on the disk, each stat(2) needs one disk seek.Here are some solutions I had in mind, none of which I am satisfied with:Create the filesystem on an SSD, because the seek operations on SSDs are fast. This wouldn't work, because a 2TB SSD doesn't exist, or it's prohibitively expensive.
Create a filesystem which spans on two block devices: an SSD and a disk; the disk contains file data, and the SSD contains all the metadata (including directory entries, inodes and POSIX extended attributes). Is there a filesystem which supports this? Would it survive a system crash (power outage)?Use find /media/myfs on ext2, ext3 or ext4, instead of ls -laR /media/myfs, because the former can the advantage of the d_type field (see in the getdents(2) man page), so it doesn't have to stat. Unfortunately, this doesn't meet my requirements, because I need all file sizes as well, which find /media/myfs doesn't print.Use a filesystem, such as VFAT, which stores inodes in the directory entries. I'd love this one, but VFAT is not reliable and flexible enough for me, and I don't know of any other filesystem which does that. Do you? Of course, storing inodes in the directory entries wouldn't work for files with a link count more than 1, but that's not a problem since I have only a few dozen such files in my use case.
Adjust some settings in /proc or sysctl so that inodes are locked to system memory forever. This would not speed up the first ls -laR /media/myfs, but it would make all subsequent invocations amazingly fast. How can I do this? I don't like this idea, because it doesn't speed up the first invocation, which currently takes 30 minutes. Also I'd like to lock the POSIX extended attributes in memory as well. What do I have to do for that?Use a filesystem which has an online defragmentation tool, which can be instructed to relocate inodes to the the beginning of the block device. Once the relocation is done, I can run dd if=/dev/sdb of=/dev/null bs=1M count=256 to get the beginning of the block device fetched to the kernel in-memory cache without seeking, and then the stat(2) operations would be fast, because they read from the cache. Is there a way to lock those inodes and/or blocks into memory once they have been read? Which filesystem has such a defragmentation tool?

Oct 11, 2010I have 4 primary partitions on my hard drive. One of these partitions has been divided into 3 logical partitions with some free space left over.

I tried this by booting a live CD and starting GParted but it didn't give me the option to increase the size of my home partition or the primary partition as a whole. The only thing it would let me do is decrease the size of my home partition.
