cockpit is intended as a replacement for virt-manager. When it fails, I
suggest you fall back on the tried-and-tested approach.

KDE in EL7 is a bare minimum. I was replacing it with:
https://copr-be.cloud.fedoraproject.org/results/rdieter/kde4/epel-7-x86_64/ but
it hasn't had any updates since 2018 I think.

[CentOS] Mostly better: new C7

[mark]

Well, I gave up, and reinstalled C7. This time, I realized I needed to 
make a software choice before the install, and did so.


My install, yesterday, was a minimal. Silly me, yesterday, after that, I 
did a groupinstall of KDE Plasma Workspaces... and it did *NOT* include 
all the dependencies to run KDE.


Having installed a KDE desktop, much is better... with one exception: I 
can't seem to find any games. I tried yum groupinstall "Games and 
Entertainment", which showed when I did group list... and was told it 
was empty.


Now what am I missing? I do have epel and rpmfusion, both free and non-free.

That's not always the best test, you should look for the existence of
/sys/firmware/efi to determine if you're using an EFI system.

'grubby' knows to update the configuration file for Legacy vs. UEFI.

Well, yes, I remember that it didn't work for me when I installed new
servers one or two years ago, that was with CentOS 7 and they were my
first EFI installs.

I have restored the original configs after messing with grub2-mkconfig and
only used kernel installs to further modify grub config. That way it has
always worked for me. And I was a bis scared by the whole EFI, grub2 and
everything around it because I felt I don't really understand how it all

I think i might have solve it.

For some reason grub2-mkconfig doesnt work.  (Have no idea why)

I manage to solve it with grubby.

sudo grubby --args="intel_iommu=on" --update-kernel=ALL

For some reason it works. I dont know if it works if my kernel gets
upgraded.

I tried this with a fairly busy and rather large database server (ok, it
was a database server running a simulation of a production workload) and
LVM (with either ext4 or xfs)  and found LVM snapshots to be completely
unworkable under busy 8K block random write workloads

now, ZFS does snapshots very nicely

What happens when you run

mount -t cifs //192.168.1.200/mp3 /home/plex/Musique --verbose \
  -o username=plex,password=plex,domain=DERWAEL,ro,auto,vers=3.0

Try removing non-ascii characters from your mountpoints and try again.

Instead of user=, try username=.  mount.cifs(8) states:

   While some versions of the cifs kernel module accept user= as an 
abbreviation for this option, its use can confuse the standard mount program 
into thinking that this is a non-superuser mount. It is therefore recommended 
to use the full username= option name.

When you look at /boot/efi/EFI/centos/grub.cfg, do you see that the
parameter has been added?

[CentOS] IOMMU and kernel

[Georgios]

Hi.
Im trying to set intel_iommu=on on kernel parameters at grub but for
some reason it doesnt work.

I edit /etc/default/grub file and i add the parameter.

then i run grub2-mkconfig -o /boot/efi/EFI/centos/grub.cfg and then i
reboot.

when i run virt-host-validate i get 

QEMU: Checking if IOMMU is enabled by kernel: WARN (IOMMU appears to be
disabled in kernel. Add intel_iommu=on to kernel cmdline arguments)

when i edit the grub menu durring boot and i put intel_iommu=on and the
i run again virt-host-validate i get

QEMU: Checking if IOMMU is enabled by kernel: PASS


any ideas?

I tried editing other variables like GRUB_TIMEOUT and it seems to me
that changes are applied.

Thanks in advance

I have commented out the 2 mounts with non-ascii... that didn't help...

Try removing non-ascii characters from your mountpoints and try again.

Do the directories /home/plex/Musique, /home/plex/Vidéos and
/home/plex/Séries really exist on the C8 host?

Since no one else has mentioned it as a solution, I've been using amanda

Hi,

starting with the easy bit: (3) selinux is disabled, and F/W is (for the
time being) stopped as well

(2) smbclient can access my cifs shares... no sweat...
[root@plexvm ~]# smbclient //192.168.0.200/mp3/
Enter SAMBA\root's password:
Try "help" to get a list of possible commands.
smb: \> ls
  .  DA0  Sun Mar 29 15:21:54 2020
  .. DA0  Thu Mar 26 11:28:36 2020
  T  DA0  Thu Jun 20 09:53:40 2019
  W  DA0  Thu Dec 19 11:28:50 2019

  F  DA0  Mon Mar  9 14:08:49 2020
  N  DA0  Thu Mar 12 09:54:55 2020

11523186296 blocks of size 1024. 3135971700 blocks available
smb: \>

as for (1), if I understand well, the 5th field is optional and it is used
to determine if the fs needs to be dumped
The 6th field is also optional and controls the fsck. As the fs is remote,
I don't want my C8 box to fsck it
That should be ok then...

Then again, to get a _really_ consistent backup, you can only terminate
all applications who read/write files, or instruct the applications to go
into a state which allows consistent file backups. Of course after the
backup you have to instruct the applications to go on with the work. You
can not achieve this consistency even with freezing _all_ filesystems
simultaneously. That's why usually RDBMS's and other more complex
applications provide their own backup mechanism embedded into the
application.

That's why rsnapshot backups are not so much worse than filesystem snapshots.

Simon

I don't know the answer, but a thought or three:

1. the entries for the cifs mounts don't have the last two fields specified. I 
dunno if they're absolutely required, so it may not mean anything.
2. you might want to experiment with the smbclient tool to see if you can
learn anything from its responses when trying to access the remote.
3. also verify that seliinux is not blocking the access.. I've had at
least one case in which I spent hours banging my head, only to discover
it was selinux and not anything in Samba.

Good luck!

Fred

[CentOS] Mounting CIFS shares on C8

[Patrick DERWAEL]

Hi all,

I'm tearing my hair off trying to understand the difference between C7 & C8
for mounting a cifs FS with fstab

I'm building a Plex media server on C8 and duplicated the fstab entries
over from my current C7 installation
My data (music & movies) are on CIFS shares on a Synology NAS.
The packages cifs-utils samba-client samba-common are installed, up to date
etc...

These are my current fstab entries on the C7 box

//192.168.1.200/mp3 /home/plex/Musique cifs
user=plex,pass=plex,ro,auto,vers=3.0
//192.168.1.200/videos /home/plex/Vidéos cifs
user=plex,pass=plex,ro,auto,vers=3.0


On my C8:

[root@plexvm etc]# cat fstab

#
# /etc/fstab
# Created by anaconda on Fri Apr  3 14:02:23 2020
#
# Accessible filesystems, by reference, are maintained under '/dev/disk/'.

It isn't just databases - there are other things that backing up
individual files one at a time is not so good.  The best way to handle
that is to freeze/snapshot the whole filesystem, and then back up the
snapshot.  This can be scripted pretty easily if the filesystem is on
LVM.

Even better is to freeze _all_ filesystems simultaneously - this is
usually easiest if the system is a virtual machine and/or the storage is
on a SAN with snapshot capabilities.

Long ago I learned to back up databases by dumping them (with a flag 
"lock" or similar to make sure no changed are made during dump), and 
backing up dump file.


Just my 2 cents.

For a full backup, I'd use something like "scp -rp". Anything else
has overhead you don't need for the first copy.

Also, pick a good cipher (-c) for the ssh/scp commands -- it can improve
your speed by an order of magnitude. Here's an example where I copy
my current directory to /tmp/bkup on my backup server:

I avoid block-level deduplication as a general rule -- ZFS memory
use goes through the roof if you turn that on.

rsync can do the hardlinks, but for me it's been much faster to create
a list of SHA1 hashes and use a perl script to link the duplicates.
I can send you the script if you're interested.

This way, you're not relying on the network for anything other than the
copies; everything else takes place on the local or backup system.

I've never had a problem with rsync, and I've used it to back up Linux
workstations with ~600Gb or so. One caveat -- if you give it a really
big directory tree, it can get lost in the weeds. You might want to do
something like this:

1. Make your original backup using scp.

2. Get a complete list of file hashes on your production systems
using SHA1 or whatever you like.

3. Whenever you do a backup, get a (smaller) list of modified files
using something like "find ./something -newer /some/timestamp/file"
or just making a new list of file hashes and comparing that to the
original list.

4. Pass the list of modified files to rsync using the "--files-from"
option so it doesn't have to walk the entire tree again.

Good luck!

Hi Karl,

thank you for your answer. I'm trying ssh scripted rsync using a faster 
cypher like you suggested and seems that transfer on 10GB is better of 
default selected cypher (129 sec vs 116 using aes128-gcm, I tested this 
multiple times). Now I will try to check on the entire dataset and see 
how much benefit I gain.


Waiting that, what do you think about bacula as backup solution?

Thank you in advance.
