Is there a limit to the number of snapshots that can exist on a file system concurrently? Did I read something here recently about a limit to the number of paths by which a file could be known? If there are limits, then what happens when I bump into or exceed that limit? --rich -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to

Greetings - Ok, I made a mistake that I need to fix. Fortunately it is not a destructive mistake, but I need some advice on how to correct the problem. CentOS 6.3 host system named Earth I was creating some new logical volumes within my exiting volume group for a new virtual machine using the LVM GUI. When I created the LV that I plan to use for root partition of the new VM (Bacteria) I

Hi all, i?m not sure if my problem is realted to ocfs2 or to drbd, so i x-post this post to both lists. I?ve drbd-volume [v 8.3.9] (dual-primary) with ocfs2 [v 1.6.3] as a filesystem. If I add a "bind-mount" like /var/log/ispconfig/httpd/blog.schaal-24.de /srv/www/clients/client2/web323/log none bind,nobootwait 0 0 to /etc/fstab i`m unable to run umount /srv/www (which is

Is there any method of forcibly umounting an NFS mounted directory? We have a test environment managed under puppet that is also our DR environment. In a DR scenario we''ll be umounting all NFS shares from out test array and remounting to our DR array. However, as this is a test environment we have users logged on, so when Puppet attempts to unmount the test directories, it fails

Doing this would reliably fail with -EBUSY for me: # mount /dev/sdb2 /mnt/scratch; umount /mnt/scratch; mkfs.btrfs -f /dev/sdb2 ... unable to open /dev/sdb2: Device or resource busy because mkfs.btrfs tries to open the device O_EXCL, and somebody still has it. Using systemtap to track bdev gets & puts shows a kworker thread doing a blkdev put after mkfs attempts a get; this is left over

So if you have a mount command that doesn''t use /etc/mtab then it will spit out a different device for the mounted device. So say we have SCRATCH_DEV_POOL="/dev/sda /dev/sdb /dev/sdc" we will turn this into SCRATCH_DEV="/dev/sda" SCRATCH_DEV_POOL="/dev/sdb /dev/sdc" and then when you mkfs this you do _scratch_mkfs $SCRATCH_DEV_POOL which turns into this

I have mounted a win98 machine from a ML8.1 samba 2.2.2 The win98 machine, as all windows machines do, crashed on me. Now i can't unmount the mounted folder, If i do it from cli, i get umount usr/Cad12: device busy. If i try and cd to that folder, the console freezes and only kill application will shut it down. I tried as su and on another Virtual console as root, but it will not umount.

* PATCH FOR DISCUSSION ONLY - NOT TO BE APPLIED * Colin suggested something which seems eminently sensible: https://bugzilla.redhat.com/show_bug.cgi?id=916780 I've been through a couple of rounds of trying to implement this. I started with adding the option as suggested to the guestmount program, but it tended to make the guestmount program more complex. More importantly, adding the option

The inode eviction can be very slow, because during eviction we tell the VFS to truncate all of the inode''s pages. This results in calls to btrfs_invalidatepage() which in turn does calls to lock_extent_bits() and clear_extent_bit(). These calls result in too many merges and splits of extent_state structures, which consume a lot of time and cpu when the inode has many pages. In some

when you have something smbmounted with samba.. //ADMINISTRATOR@CALVIN_SR/M$ 112G 71G 41G 64% /mnt/samba and you unmount it and it gives you /mnt/samba is busy Im absolutely positive that I am NOT in the /mnt/samba dir, nor is anyone else. is there any way to force it to unmount? Jason

Since the first patch: - The program is now called 'guestunmount'. - I tested the --fd option and it appears to work. - You can now control retries / quiet. - Revised man pages. - Includes tests. I'm just running through the automated tests now. Rich.

Hi all! What's the best way to stop the CLIENT process for Gluster? We have dual systems, where the Gluster servers also act as clients, so both, glusterd and glusterfsd are running on the system. Stopping the server app. works via "/etc/init.d/glusterd stop" but the client is stopped how? I need to unmount the filesystem from the server in order to do a fsck on the ext4 volume;

It works, but I should delete if (guestfs_umount_all (destg) == -1) ??? exit (EXIT_FAILURE); inmain() function and /* Clean up. */ ? if (guestfs_umount_all (srcg) == -1) { ??? pthread_cancel (threaddata->mainthread); ??? exit (EXIT_FAILURE); ? } in the start_scrthread() function or it will return an error after the program finish: libguestfs: error: umount_all: umount:

This occasionally happens to me when I've been editing an OOo document that resides on a flash drive I use with one of my laptops. I've tried poking around in ps to find out which process has the drive locked, and I can't figure it out. Nothing directly refers to the flash drive except one of the hald processes, and it's just scanning the drive (I tried killing that and it made

Hi All, How do I unmount an NFS share when the NFS server is unaivalable? I tried "umount /bck" but it "hangs" indefinitely "umount -f /bck" tells me the mount if busy and I can't unmount it: root at saturn:[~]$ umount -f /bck umount2: Device or resource busy umount: /bck: device is busy umount2: Device or resource busy umount: /bck: device is busy This
