I am looking for explanations on how Opensuse utilizes the root directories. Like what decides if a program goes in /bin vs /sbin vs /usr/bin etc...In other words, a breakdown of the directory structure and how each part is utilized. I am trying to get more familiar with it so it will be easier for me to locate things and I will know where to look for X part of a program that does Y.
View 3 Replieshaving repartitioned a disk yesterday but uwisely not obliterating a DOS OEM partition, came down to find the machine had woken up & booted the wrong disk (one I partitioned but without ne OS); with apparently dead (unwilling to seek main drive).
Trouble is the OEM diagnostics was old DOS and likes to **** on other disk partition tables and it seems to have got run, from what was the OEM Windows disk. Now I've fixed that, it seems to be screwed partition table issue.
No problem, it happened before and I recovered with gpart(8) & a spot of tweaking, but due to "redevelopment" I've now got my partition table backups on the disk that's lost. The old backup of them, got tidied. gpart's for once only finding the partitions I don't care about eg) swap & a Windows 7 NTFS backup partition.
Have some logfiles from 11.1 days, which may if it gets recorded somewhere by YaST or other in /var/log actually have the table output. Any one happen to know, where to look as a time saver?
I'd like to get these system partitions back, as I put in bugs on 12.1 M2, as well as an 11.4 and older 11.2 install for comparison. Wasn't planning on re-installing, when I get asked to try something later on.
I have a home storage of many drives which are seldom accessed, and extremely seldom written to. So, I made several RAID1 arrays with "write-mostly" drives in each one, so that all the drives spin down after a while, and if they are accessed, only one drive in each array has to spin up. This way, I hope to minimize the risk of losing anything due to mechanical shock or wear.
But it was not so easy. First, the write-mostly drives did spin up on every read request due to a bug in the kernel, so I managed to get the fix accepted into the newer kernels (which is my largest contribution to the Linux development so far. See [URL] .....) Now, if I read directly from the array, it works as expected (only the first drive spins up); but if I create a filesystem there (ext4) and read from it, the second drive still spins up anyway. (Does ext4 write something when it reads a file?.. I have it mounted with relatime, so AFAIK it shouldn't...)
Well, I thought, I'll just mount the filesystems read-only and remount them if I need to modify the data there, which is not very often, to say the least. Also, this way the drives don't have to spin up every system shutdown to unmount the filesystems; during a power outage, it used to take a lot of time for them to spin up one by one just to unmount, while my UPS had to survive long enough for them to finish. That's one more problem solved.
But I decided to improve even further. Sometimes I just want to see the contents of those arrays without even accessing some files (for example, when I accidentally click the wrong network drive button in Windows, or when I just want to see if I have something there or not). If I read the directory trees during startup and keep them cached, then those drives won't even have to spin up at those moments! The question is, is there a way to do it? I remember Linus boasting about our kernel being the best at caching the filesystem trees, and I know there is vmtouch [URL] .... which allows us to keep some files cached, but what about the directory tree itself?.. If I simply "find" all the files there, it seems to work, but they get evicted from cache sooner or later...
I've got a directory structure full of files. I want to convert them all into some other format, but I don't know how to keep the directory structure, is there a way so I can "set" which command to use on files instead of `cp`?
View 4 Replies View RelatedAre there any other archiving tools than tar that preserve Linux file permissions and user/group flags? I want to create archives of a directory tree on my ubuntu box. The directory trees are large, a first run with tar cvpzf archive.tgz /home/foo/bar yielded a 5GB archive. I also want to keep all permissions and other flags and special files.I'm fine with a 5GB archive, however to look inside that archive -- since it is a compressed tar archive -- the whole 5GB have to be decompressed first! (Or so it appears when opening it with the archive viewer -- I'm happy to be corrected.)So I need a way to "backup" a directory (tree) while preserving full filesystem attributes and right and creating an archive with an "index" that hasn't to be decompressed for browsing its contents. An archive is either a single file, or a (small) set of files that carries full and complete information within this file/s. That is, it can live on any filesystem (size permitting), it can be burnt onto a DVD, you can split it (after which the point of this question is really lost - but still), ...
View 3 Replies View RelatedI have a WD world book edition 1TB NAS drive, and just purchased an acomdata 1tb drive and connected it to the NAS via USB. If I recall I think the WD NAS has a ext_ or some type of linux filesystem on it, and the acomdata has a ntfs filesystem on it.
What I want to do is copy over certain directory trees of the NAS to the USB attached drive. I usually use MS synctoy to sync folders from my windows pc to the NAS drive, and MS richcopy to make the initial transfer from PC to NAS. For this operation though, since it is taking place entirely on the NAS and its connected drive, I thought that rsync would be the best option, and it is available on my NAS drive.
Last night I entered in rsync -avr /movies/* /usb1-1share1/ to copy the entire "movies" dir to the drive, which shows up as usb1-1share1 on the NAS drive. It copied most of the directory tree ok, but a lot of the folders were empty, so this morning I tried rsync -Carv --ignore-existing /movies/* /usb1-1share1/ to try and get all the files missed, without recopying the 24GB that did make it across. This also managed to copy a few more GB over, but not everything.
I am running the command from an ssh session on the NAS using putty on my PC, in as user "admin" which should have all rights over these folders. There is a bunch of errors in the command window like this: rsync: failed to set times on "/shares/usb1-1share1/movies/classics/fulldvd/First Blood DVD/.VTS_01_2.VOB.RxdjWZ": Operation not permitted (1)
I want to restart another session and get the files it missed, but I want to find out what I am doing wrong first. Should I be doing this as root user? am I missing some switches or just plain doing it all wrong?
I am trying to ftp a whole directory tree using vsftpd as ftp server in fedora11

This little fragment does the opposite of what I want and I am trying to figure out how to reverse it. I want to strip off the directory and echo just the filenames. I cannot predict how many levels deep the directory tree is.

I would like to overwrite files in a directory tree, recursively. The ones I would like to overwrite match the filename "x_alpha*.png" and have a size exactly 456 bytes. Is there any way to search for these recursively in a directory tree, and overwrite them with a reference file, for example "e:mydirgood.png"

I have ubuntu 9.10 & windows 7 on my laptop. I have one 40GB Primary partition (C & 60 GB logical partition on my windows. I have given another 20GB for ubuntu.
I hibernated my windows7 & then started ubuntu 9.10. Then I copied a folder containing some PDF files from my ubuntu to that 60GB (D on windows. Then I rebooted the machine & choose windows from GRUB. the windows came up from hibernation but nowhere I was able to see that folder which I copied.
Since ubuntu supports (understands) NTFS file system it means when I copied that folder it should have updated the Directory Tree of NTFS on that 60GB (D but that folder is not shown.
When I restart the windows the folder appears (ofcourse because windows checks the file system again for consistency while in hibernation it does not).
I have a user account (no root access) on a Debian system. My disk quota for my home directory is limited to 250MB, of which I've used 150MB.
I would like to install a program that requires 95MB of space (let's call it prog-5.1) into $HOME/local/bin. Because the source files take up 1GB, I've had to place them in the /tmp directory (to stay under my limit).
Unfortunately when I run the config script, I receive the following:
Code:
The reason for this is that /tmp is mounted in noexec mode, meaning I can't execute code in /tmp directory:

I'm wondering if anyone has any ideas about running the config script in my home directory, and somehow pointing it to configure the files in the /tmp/prog-5.1/ directory.
I found it easiest to embed narp into the gtk+-2.0 installation because all I needed to do was tweak the Makefile.am and Makefile.in files and let configure do the rest.This is a hack. I've failed at getting my own makefiles to work.

I downloaded it, is the intent that you just install all of the RPMs in the RPM directory? There isn't too much documentation yet.
so i cannot install anything because update-info-dir file is missing from /var/lib/dpkg/info/ ..

Search for "file-browser-applet" in the Synaptic Package Manager. The applet with exactly that name is what you need. It allows to browse and open files on your computer from the GNOME panel. Once installed, "Add to panel".
I have 3 disks in my PC which are partitioned equally as I use them for Raid 1.The first partition on every disk is a simple ext2 partition for booting. No Raid there. So I mount them as /boot and /boot2 and /boot3. So I can backup my /boot to the other boot directories. That worked for some month and this morning I just want to look if all directories have enough free space left. So I did a df -h and got this:
Code:
Dateisystem Grove Benut Verf Ben% EingehÃĪngt auf
/dev/mapper/system-root
6,0G 301M 5,4G 6% /
udev 1,5G 292K 1,5G 1% /dev
/dev/sdb1 122M 29M 87M 25% /boot
/dev/sdc1 38M 21M 16M 59% /boot2
...
/dev/sda1 122M 29M 87M 25% /boot
As you can see /dev/sda1 and /dev/sdb1 are both mounted on /boot
Here is what mount says:
Code:
/dev/sdb1 on /boot type ext2 (ro,acl,user_xattr)
/dev/sdc1 on /boot2 type ext2 (ro,acl,user_xattr)
...
/dev/sda1 on /boot type ext2 (ro,acl,user_xattr)
This is no Problem for me as I could just remount it correctly, but I would like to know if this problem is known. I did not change anything by now and this PC is a server which is running 24/7, so I can deliver more debugging Information if someone is interested.

I am having a problem setting up an encrypted home directory with openSUSE 11.3. I used Yast User and Group Management to edit an existing user to encrypt the home directory and the user.key and user.img files were created in the /home directory. I tried it out and logged in as user and created a new file. I logged out and logged in as a different user and was able to see the newly created file in the first users home directory.
I figured I did something wrong so I went back to Yast and deleted the user. I deleted the /home/user directory using file manager su mode. I tried again to create a new user with an encrypted home directory using Yast and now when Yast tries to write the changes I get an error: "pam_mount is already setup for user. Use --replace to replace the
existing entry." I do not know how to proceed from here except to try with a different user name as I do not understand what the error message means and what command to use --replace with.
