similar to: rsync --delete with empty source folder for fast snapshot deletion: Permissions of hardlinked files are changed to 644. Workaround?

I had intended to come back to this but because I didn't really think I had anything to add to the discussion I put it at a low enough priority that I forgot about it. But I saw your bug report and was surprised to see that I was already unhelpful on this topic but because that original poster didn't have access to do an rm while you are trying to get a performance boost. I have

So I decided to do a quick test using the Linux kernel source tree since it has lots of files. I duplicated a tree, used 'find . -type f -exec chmod 444 {} +' to make read only files for rsync to want to chmod, then used cp -al to make several duplicate trees using hard linked files. An rm -rf on one such tree took .97 seconds while an rsync deletion took 1.25 seconds. Clearly I

This **may** indeed be a myth (for a long time now) re-cited again and again and - could no longer be valid today - could apply only

Hi, i just realized that i have a guest with two disks. What would be the appropiate way to snapshot both of them ? virsh snapshot-create-as --domain guest --diskspec vda,file=/path/to/snapshot/snapshot1.qcow2 -disk-only --atomic && virsh snapshot-create-as --domain guest --diskspec vdb,file=/path/to/snapshot/snapshot2.qcow2 -disk-only --atomic or virsh snapshot-create-as --domain

Hi everyone, Is there an easy way to find out which files has changed between two snapshots? Currently I''m doing a # rsync -arvn <snapshot1> <snapshot2> and it creates a list. But rsync needs to go through the whole filesystem and compare files. It would be nice if zfs would have this option builtin. Regards, Nickus

Hello, I have a Windows 10 guest, when I boot it, it goes in to Automatic Repair mode, and after some time reports it was unable to repair the PC. This is from an older snapshot ("snapshot1"), and if I try switching back to a more recent snapshot ("snapshot2"), libvirt reports that it can't find the snapshot: > libvirt.libvirtError: internal error: Child process

I am unable to convert a vm using virt-v2v. From the trace and debug logs I am unable to understand the cause of the problem. I assume it is a permission or configuration issue but I don't know where to start looking. The following command was issued: LIBGUESTFS_TRACE=1 LIBGUESTFS_DEBUG=1 virt-v2v -ic qemu+ssh://xxx at 192.168.xxx.xxx/system -o rhev -os 192.168.xxx.xxx:/mnt/exports -of

I am trying to run a 2d overhead ultima type game through wine but have some problems. At one point it would run but would refresh the slides of the pictures about once every 5-8 secs and then crash after about a minute or so.

I''ve been saving up a few wishlist items for zfs. Time to share. 1. A verbose (-v) option to the zfs commandline. In particular zfs sometimes takes a while to return from zfs snapshot -r tank/volumes at foo in the case where there are a great many iscsi shared volumes underneath. A little progress feedback would go a long way. In general I feel the zfs tools lack sufficient feedback

I use Gentoo Linux, with an up-to-date installation of Gentoo and Wine. I downloaded Winetools, and ran it. To make a long story short, I can't get any fonts or text in any 'Windows' dialogs, windows, etc. (Except for the title bar) I have tried literally EVERYTHING to solve this problem. I 'googled' for other people having the same problem, installed Arial and the other

I found a strange bug in R recently (version 3.1.2): As you can see from the screenshots attached, when the cursor passes the right edge of the console, instead of start on a new line, it goes back to the beginning of the same line, and overwrites everything after it. This happens every time the size of the terminal is changed, for example, if you fit the terminal to the right half of the

I have wrote a small Linux Shell command for implementing Interlock Protocol which is known as a cryptographic protocol that resistant to man-in-the-middle attack. Here is the steps of interlock protocol: *(1)* Alice send her public key to Bob *(2)* Bob send his public key to Alice. *(3)* Alice encrypts her message using Bob's public key. Then she sends half of that encrypted message to

Hi *, it seems rsync with --fileflags isn't able to work on (already) hardlinked and immutable ("schg") files on FreeBSD. The following scripts will create a simple example for this behaviour: -------------------------------------------------------------- #! /bin/sh # # set -x DIR="/var/tmp/rsync_$(date +%s)/" mkdir "${DIR}/" # Preparing dir_A mkdir
