I have installed Debian through the Debootstrap process using the ext4 fs for root and it worked without a problem. When I tried to install Debian mounted on btrfs subvolumes, there are problems mounting root while booting so it crashes... Any clue if Debian supports btrfs subvolumes?
View 5 RepliesThere are a couple of way to mount Samba shares, but I prefer using "autofs" which can mount them on the fly. Use the autofs daemon to have shares automatically mounted on demand. The netfs service (installed by default in Fedora) is not a daemon and can only mount shares on boot, (it can't mount them on demand).
* Install the autofs package:
Code:
yum install autofs * Edit /etc/auto.master (the master map file), and comment out all lines (with #). This avoids conflicts with the CDROM (which is handled by Gnome), etc. Save the file. * Create a new file /etc/auto.cifs, with the contents of:
Code:
#!/bin/bash
# $Id$

I'm using fedora core 9 and I am a linux beginner. In my computer, I can see the icons representing windows partitions but cannot be opened. I right click on it and then opt for "mount the volume" . But there is no use. What can I do?
View 2 Replies View RelatedI have created lvm snapshot, its dd file and .tar.gz files are on lvm volumes. Snapshot is of / directory, is residing in lvm volume. The root directory is also lvm volume. So I was trying to restore from snapshot of / using live cd of rhel5 BOOT.iso. which i found it in /rhel5_dvd/images/. The tutorial I was following said that the live cd should support lvm. So when I am trying to restore after few steps when it asks for media which contains rescue image, I was unable to see the lvm volumes created earlier, instead it shows the partitions added to physical volume earlier i.e., #pvcreate only. So I wanted to know whether the live cd of rhel5 supports lvm or I am making some mistake in restore?

and I'm dumped into recovery mode. However, if I remove these mounts from /etc/fstab via comments, I can wait for the system to boot (which it does very quickly) then mount the mapper devices myself. So what is going on? Has something changed wrt logical volumes, or is this just systemd? I can live with manual mounting, but any advice on resolving the automatic mounting situation would be great.

My goal ist to install Debian Jessie on a drive with a btrfs subvolume scheme. This is my first time using btrfs and also my first Jessie installation.
My experience is, that partman creates btrfs file systems but doesn´t support btrfs subvolumes (why not?).
I successfully created btrfs subvolumes manually in a shell session during ("expert") installation and manually mounted them to the desired mount points in /target. Installation went through until grub2 installation, which failed.
Is there a best practice to install Debian (Jessie) on a btrfs file system with subvolumes? I want to use subvolumes for /, /home, /var/log and /var/lib/mysql.
will going from 10.04 desktop to 10.10 netbook mean i have to reinstall everything? also, does the netbook version support mounting of networked drives?
View 3 Replies View RelatedI have done a recent install of Debian squeeze on a laptop. I set up LVM with 3 LV's, one for the root filesystem, one for /home, and another for swap. I then used lvextend to increase the size of the LV's. This additional space is shown if I enter lvdisplay (shortened for clarity):
- Logical volume -
LV Name /dev/auriga/swap
LV Size 4.66 GiB
- Logical volume -
LV Name /dev/auriga/root
LV Size 15.97 GiB
- Logical volume -
LV Name /dev/auriga/home
LV Size 169.01 GiB
However, if I use df, it still shows the previous size.
/dev/mapper/auriga-root 14G 8.0G 5.2G 61% /
/dev/sda1 221M 16M 193M 8% /boot
/dev/mapper/auriga-home 147G 421M 139G 1% /home
I have even tried restarting as well. I do not understand why df would still show that /home is 147GB, when I extended it to 169GB using lvextend. Similarly for the root, which was extended by 2GB from 14GB to 16GB.
I have let the debian installer set up with separate partions forrootusrvarhometmpIt ended up with a huge home partition and little place for the others.So I wanted to give some of home's space to the others and didlvreduce on homelvextend on the others.Following some info on the net it tells you toe2fsck -f partition1 followed by aresize2fs partition1But when I try to fsck the reduced home partition I got the following error:The filesystem size (according to the superblock) is 73113600 blocksThe physical size of the device is 20447332 blocksEither the superblock or the partition table is likely to be corrupt!Abort? yesIs there any way to save this?
View 5 Replies View RelatedThings were fine for a couple months until this most recent dist-upgrade. The new grub has an incompatibility with BTRFS which nearly caused me to lose everything, as grub couldn't set up the boot system since it can't see the BTRFS partition. I worked for days trying to get help in the linux-btrfs listserv, but they don't seem to understand Debian/Ubuntu, and they kept referring me to Debian and grub devs. I asked them how those devs will know any more about BTRFS than they do, but there was no reply.
They said the new grub (1.99~rc1-13) will fix it, but unfortunately the Debian package management system was jammed by BTRFS as well and I couldn't install/deinstall anything. I finally had to unpack the grub-pc .deb and manually install it, but guess what? It didn't fix the problem. I've now had to completely rebuild my system without BTRFS. This has cost me days, which I cannot spare. I realize it says 'experimental' on the BTRFS website, but it is in the stable kernel, and there is not a word anywhere about it being completely non-functional in Debian/Ubuntu.

I'm looking to dual-boot Windows 7 and Debian 6 upon its release on my sister's laptop. I want to share a partition between the two of them so that /home points to this directory and the Windows equivalent also points to it (C:Users).
Anyway, I've heard good and bad things about the NTFSMount driver (I think it's NTFS-3G now) and the NTFSprogs project and so I am not so certain what I should believe. I do know that NTFS has relatively high overhead, though I do not recall the source of this assertion, so I am considering the use of EXFAT. An open source EXFAT project is hosted on Google Code at [url] and it utilizes the kernel module FUSE.
I'm quite certain that I've got everything covered on the Windows side -- that is, I know that both NTFS and EXFAT will be suitable filesystems for my required usage.
My issue is that I'm curious which will have superior performance and stability in Debian. I planned on building the package from source and mounting the device in my FSTAB but I have also found a PPA for Ubuntu on Launchpad at [url] that I could borrow the debian/rules from and make a .deb package from.
What do you guys think? Should I go at it with the EXFAT or NTFS partitioning? Is NTFS-3G actually fairly supported at this point? Or perhaps should I consider some alternate method?
I have also considered that the only files she will be sharing are those of music, videos, and pictures so it could be better to just link /home/xxxx/Pictures (Music and Videos, too) to the new partition instead of all of /home.
I'm having some issues with audio crackling/buzzing when turning up the volume, or on songs that have overclipped / overdriven parts, which doesn't happen on Windows (on it those sections are just "dampened"). Is there some certain settings in ALSA that are used to deal with this? Or is it something specific to the driver for the hardware? Speaking of which I'm using some integrated audio which goes by the name of Intel ICH7, and the chip itself is Analog Devices AD1981B.
I'm only using ALSA, without PulseAudio, and I've made sure the volumes both in the media players and under alsamixer aren't turned too high (PCM is at 47% and "Headphones" -- what is "Master" on Windows and on other soundcards under Linux -- is on 22%), so it isn't an issue with the software mixer being turned up too high. Also I'm using a pair of quality headphones (Sony MDRV55) so it's not an issue with the analog audio output either. I've also tried multiple other headphones and the result is the same.
I will be installing Fedora 15 on my work laptop this weekend and am wondering: Could I use BTRFS as the default filesystem? Why or why not?
My default layout looks like this:
/boot
LVM
swap
/
/home
This would mean that all the LVM partitions would become BTRFS. Or maybe only the /home would become BTRFS.
Different threads state that you shouldn't use BTRFS yet on production systems, but there are also plans to include it in F16 as the default FS.
Why should (or shouldn't) I use BTRFS as opposed to EXT4?
I am about to setup a computer with Maverick. This will be for experiment use only, there will be nothing of any critical nature on it. Should I consider using the BTRFS, yes or no ? What would be the advantages/disadvantages (if any) on using it as opposed to EXT4 ?
View 4 Replies View RelatedI'm just diving in to figuring out how to partition/utilise BTRFS.I am used to just installing with EXT4 and carving out a / and a /homeBut, from what I understand, this isn't the case with BTRFS?I know you have to create a separate /boot as grub doesn't support the file system.But, with BTRFS, we just create a / and /home and others would then just be subvolumes?What happens if I want to reinstall? I have liked being able to just wipe / and reinstall the OS, leaving my personal files in tact. Does this still happen if the /home is just a subvolume? Hopefully that makes sense

View 6 Replies View RelatedOkay, so I found a couple articles about the new BTRFS for Ubuntu that became available on 10.10, and I was wondering if some people could clear some stuff up for me. I am going to be upgrading my desktop box from 8.04 soon (I know,long time coming, but I had some hardware compatibility issues with recent releases that have been addressed on my end) I'm pretty new to a lot of these terms, so a detailed explanation would be awesome if you don't mind.
1 - Is this file system ready for the home user?
2 - Are there significant performance gains over ext4 and is it stable? If not now, will it be in the future?
3 - When a new subvolume is created, does that act like a partition? For instance, would a home folder in it's own subvolume act like home on a separate partition in the event of a reinstall or upgrade to the root filesystem? If not, what would be the specific advantages to using a subvolume?
4 - When creating a snapshot, is it bit for bit or a compressed image?
5 - Does compressing the root filesystem save a significant amount of disc space?
6 - Is there anything else that would be important to know about this filesystem?
If I have some things confused or misunderstood, it is because I am just starting to understand how some of the foundational stuff in my OS works
I'm a big fan of ZFS on FreeBSD (I've been using it on my home server since before it got stable; bleeding edge, baby!) and I'd like to try out btrfs to see how that's evolving. Since it's still largely in development, none of the usual mainstream distros have btrfs as an option. I haven't used Linux in a bunch of years, so I don't really know what my best options are for giving btrfs a try.
View 2 Replies View RelatedI decided to try playing with btrfs. I think you could do lots of fancy things with that. One thing puzzles me though - I can make a snapshot or a subvolume the default volume to mount (using btrfs set-default , but how do I then remove that subvolume default so that the base filesystem is the default mount again.

I'm currently running the XFCE Spin of Fedora 15 (Xedora, as I like to call it (; ) on 64 bit, so sometimes I need a 32 bit environment to try stuff out.
I recently installed Linux Mint on a partition formatted to btrfs, and this is where my problems start, as I have no idea how to add this installation to my existing GRUB configuration. The grub.cfg on the Mint partition looks like this (GRUB2 btw.):

View 9 Replies View RelatedCurrently have multiple small DNS-323 NAS-in-a-box that need to be replaced with a single storage server.
Since the setting is for an advanced home server (2-3 simultaneous clients max) that will hold movies and application/game ISO's, I was originally going to go with a simple RAID6 on freenas. As I learned about silent data corruption, and with a max of 3 simultaneous users, I don't see a need for a hardware raid processor. So I gathered that software RAIDZ (RAIDZ2) based on ZFS or BTRFS that prevent silent data corruption would be a better match (please correct me if I am wrong).
NEEDS: The needs (in addition to prevention of silent data corruption) are basically online capacity expansion (OCE), and 2+TB volumes (64bit LBA); with a preference for the ability to spin down idle drives. I'm going to make the assumption that any solution I go with will allow me to read/monitor actual SMART drive data.
STUMBLING BLOCK(S):
1. Would someone validate the (perhaps mistaken) assumption that since BTRFS is integrated into the latest Linux kernel, it is mature enough for NAS candidacy.
2. Please validate: Forward-compatibility of BTRFS has been stated (no need to reformat with subsequent BTRFS updates).
3. Am I missing any NAS software (open-source or otherwise) that would meet these requirements and provide a nice pretty graphical interface?
4. What software solution would you recommend? (btrfs on xxxxx? zfs-fuse? linux+xfs (+mdadm)? ..?)
5. What are my next steps?

I was interested in the idea of the btrfs subvolumes, so I made a virtual machine and installed Slackware as per the instructions here: [URL] It all went very well, but when I tried to switch from the huge kernel to the generic kernel and use the initrd.gz generated from step 29 (except that I used 2.6.37.4-smp instead of whatever's there) in lilo.conf, it failed to boot. I also noticed that in the instructions themselves, the poster doesn't actually add the initrd.gz to lilo.conf, so I'm guess the huge kernel has everything it needs to boot properly.
