similar to: Question about cleanly unmounting slave bind mounts

The test program below demonstrates how to use bind mounts to mount a subdirectory over the root directory. It is using the debug backdoor, but I guess we could consider adding a bind-mount API instead. [Note that guestfs_mount_options doesn't work because it expects the third argument to be a device, not a directory name.] Rich.

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

Hi Mikkel! Yes, of course. Why didn`t I see this? Simple solution. Thank you very much for that hint!

I''m running into a situation where I can''t unmount a mounted snapshot. It shows "busy" even though neither lsof nor fuser show any open files. Umount -f doesn''t work although umount -l does. Is there anything else I can do to debug this scenario or to clear the busy status myself? Or am I down to rebooting each time? This is on stock ubuntu-10.04, x86.

I'm attempting to build a virtual disk image for qemu of CentOS4 on CentOS4. I'm having a problem after using yum --installroot to put a minimal filesystem on a partition located within the virtual disk. When I go to unmount it, I get "device is busy" errors. I know that I haven't left anything using that filesystem and lsof doesn't show anything, so I'm wondering

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

.. or just a way to make samba, when samba shares via glusterfs api, to show in a share/vol a submount(like fs bind) - how, if possible at all? I guess it would have to be some sort of crossing from one vol to another vol's dir or something, hmm... many thanks, L.

Hello everyone. I'm trying to install CentOS 8 with root and swap partitions on software raid. The plan is: - create md0 raid level 1 with 2 hard drives: /dev/sda and /dev/sdb, using Linux Rscue CD, - install CentOS 8 with Virtual Box on my laptop, - rsync CentOS 8 root partition on /dev/md0p1, - chroot in CentOS 8 root partition, - configure /etc/mdadm.conf, grub.cfg, initramfs, install

Hi In QEMU 8 virtiofsd has been removed in favor of the rust version. Which includes options that are not longer supported, Do you have a view on what should be used going forwards to support virtiofsd in libvirt with qemu 8? The options are showing as depreciated, -o <compat-options>... Options in a format compatible with the legacy implementation [deprecated] Rust
