One way to tell is to pretend things are working even if you only see garbage. For example, if you press several times, do you get the same garbage each time (likely the shell prompt coming back to you). If after an Enter and return garbage you type ls is the garbage different, probably larger, and likely ending with the same garbage as a solo (the prompt) Then try to reset your stty communication settings by carefully typing stty sane Don't try to correct typo's, just hit enter and start again. Should that not work, ssh back in and kill the shell session on ttyS0. Typically the communication settings are returned to a default set by a program called getty which then exec's into the login program.

Re: [CentOS] Upgrading system from non-RAID to RAID1
On 1/11/23 02:09, Simon Matter wrote: I plan to upgrade an existing C7 computer which currently has one 256 GB SSD to use mdadmin software RAID1 after adding two 4 TB M2. SSDs, the rest of the system remaining the same. The system also has one additional internal and one external harddisk but these should not be touched. The system will continue to run C7. trimming - I do not see any benefit to breaking up the LVM2/LUKS partition containing /root, /swap and /home into more than one RAID1 partition or am I wrong? If the SSD fails, the entire SSD would fail and break the system, hence I might as well keep it as one single RAID1 partition, or? What I usually do is this: "cut" the large disk into several pieces of equal size and create individual RAID1 arrays. Then add them as LVM PVs to one large VG. The advantage is that with one error on one disk, you wont lose redundancy on the whole RAID mirror but only on a partial segment. You can even lose another segment with an error on the other disk and still have redundancy if the error is in another part. That said, it's a bit more work to setup but has helped me several times in the decades ago. Ah, now I begin to get it. Separate partitions RAIDed. - Is the next step after the RAID1 partitioning above then to do a minimal install of C7 followed by using clonezilla to restoring the LVM2/LUKS partition?? - Any advice on using clonezilla? Or the external partitioning tool? - Finally, since these new SSDs are huge, perhaps I should take the opportunity to increase the space for both /root and /swap? - /root is 50 GB - should I increase it to eg 100 GB? - The system currently has 32 GB of memory but I will likely upgrade it to 64 GB (or even 128 GB), perhaps I should at this time already increase the /swap space to 64 GB/128 GB? I'm also interested here to learn what others are doing in higher memory situations. I have some systems with half a TB memory and never configured more than 16GB of swap. I has usually worked well and when a system started to use swap heavily, there was something really wrong in an application and had to be fixed there. Additionally we've tuned the kernel VM settings so that it didn't want to swap too much. Because swapping was always slow anyway even on fast U.2 NVME SSD storage. Perhaps you have not dealt with Firefox? :) On my Fedora 35 notebook, it slowly gobbles memory and I have to quit it after some number of days and restart. Now I only have 16GB of memory, 16GB physical swap, and 8GB zram swap. Building a F37 system now and see how that works, I doubt there is any improved behavior with Firefox.

And... I'm not sure if GRUB2 handles RAID 1 /boot fully correctly, for things where it writes to the FS (grubenv updates for "savedefault" for example). But, there's other issues with GRUB2's FS handling anyway, so this case is probably far down the list. I think that having RAID 1 for /boot and/or /boot/efi can be helpful (and I've set it up, definitely not saying "don't do that"), but has to be handled with care and possibly (probably?) would need manual intervention to get booting again after a drive failure or replacement. ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] Looking for a RAID1 box
Well I just ordered a Proliant gen10+ microserver, as the gen10 of for 1/2 the price was the $0.59 hamburger (we ad it, but you can't order it). I also ordered 4 Seagate 4T terascale drives (seems nothing smaller around). So in some 2 weeks I will have it all together and will see what happens when I do the install. :) Supposedly there is an internal boot usb port in the gen10+ On 1/6/23 09:42, Robert Heller wrote: At Fri, 6 Jan 2023 08:39:22 +0100 CentOS mailing list wrote: Hi I have found a: HPE 873830-S01 ProLiant MicroServer Gen10 for <$300 without drives. If I can believe the seller, it has a AMD Opteron X3216 Dual-core (2 Core) 1.6GHz and 8GB Installed.

Re: [CentOS] Looking for a RAID1 box
It will go into my rack cabinet so I COULD do a 1U format. I would prefer something sitting on a shelf in the rack (next to my QNAP NAS) about the size to handle 2 HD and system board. Enough memory for Centos and the mail server software. Perhaps 2Gb is enough? 4Gb nice to have (anti-virus could eat up memory at times?) Oh, has to be Intel not ARM (iRedMail req) I don't need hot swap. I just did a drive replace on my QNAP and it took ~10min to power down and swap drives. Took 10hr to mirror to the new drive. I DO want it all in the box. No external drives. And I don't want to build my own hardware. I want to buy it, install drives, attach boot ISO, and install away. Low power like 40W or less good.

Re: [CentOS] Raspberry Pi 4 and C++ 17
Did you try: sudo yum install gcc-c++ binutils libc-devel ??? Not sure what version of gcc-c++ that will get you. My CentOS 7 VPS has gcc-c++-4.8.5-44.el7.x86_64 on it, so I would assume the above should get you gcc-c++-4.8.5-44.el7.armv7hl. OTOH, my Raspberry Pi 4 build box with Raspberry Pi OS (based on Debian 10) has gcc version 8.3.0 (Raspbian 8.3.0-6+rpi1). Maybe you should just get an up-to-date Raspberry Pi OS image. Then after 'sudo apt update;sudo apt full-upgrade -y' you can do 'sudo apt install g++ binutils libc-dev'.

Does it, though?
$ bash fstab-decode.sh echo '$PATH'

After study, the only types of expansion that occur _after_ parameter expansion
are word splitting and pathname expansion, and those are both protected by the

Preface: Never heard of fstab-decode before. Researching the command made me really wonder why it
was invented. Especially since I have never seen an /etc/fstab with "escape sequences" or
"special characters" since at least 1990 (If I am wrong: Please show me such a fstab

So why not just use:
umount $(awk '$3 == "vfat" {print $2}' /etc/fstab)
instead of the seemingly canonical use of fstab-decode
fstab-decode umount $(awk '$3 == "vfat" { print $2 }' /etc/fstab)
Those samples break if the mount point directory name contains spaces, tabs, or
whatever other characters I don't know about that also get represented by
escape sequences. I'm not actually using it with /etc/fstab, but with
/proc/mounts which uses the same convention. I can control /etc/fstab and avoid
the problem, but I cannot control how some auto-mounted foreign filesystem
might be named. I have a script that needs to be robust in the face of such
names.
Get creative! Unix administration is a creative job. Having said this:
Using white space within mount points is asking for trouble anyway. If you
really want this in the most generic way, then do the unquoting with something
like this:
awk '$3 == "vfat" {print $2}' /etc/fstab | perl -pl000 -e
's/\\([0-7]{3})/chr(oct($1))/eg' | xargs -0 -n 1 -r umount
This seems to be the unixy way to do this.
Yes, white space in mount points is asking for trouble, but if someone automounts a USB flash drive
filesystem which has a label that includes white space (e.g.: "USB DISK", like the VFAT
preformat on some that I have bought) or other "funny" characters, that label gets used
as the mount point directory.
Indeed, I can re-invent the wheel if that wheel is lost in the sands of time.
It turns out that particular wheel is best resurrected from the fstab-decode.c file in an
old initscripts source package. The encoding is nonstandard, and the above perl code
would not handle it correctly. Handling the unlikely oddball case seems like severe
paranoia, but this could turn out to be, "That line of code you thought would never
be executed just might save the day that one time when it _does_ get executed."

You need to grab a copy of debmirror, which is just a Perl script, so it should work under CentOS. I don't know where to get a version as a tarball -- I had an available VM running Ubuntu and just installed it there and NFS mounted the mirror disk from the CentOS server.

Re: [CentOS] KVM vs. incremental remote backups
What *I* do for backing up KVM VMs is that I use LVM volumes, not QCOW2 images. Then I take a LVM "snapshot" volume, then mount that locally / readonly on the host and use tar (via Amanda). Another option is to install Amanda's client on the VM itself and use Amanda to use tar (running on the VM) -- I use the latter to deal with VMs that have a FS that it not mountable on the host (usually due to ext4 version issues -- CentOS 6's mount.ext4 did not like Ubuntu's 18.04 ext4 fs). I have always found using container image files with VMs a bit too opaque. Since you are using QCOW2 images, you best option would be to treat the VMs as if they were just bare metal servers and rsync over the virtual network (ala 'rsync -a vmhostname:/ backupserver:/backupdisk/vmhostname_backup/') and not even try to backup the QCOW2 image files, except maybe once in awhile for "disaster" recovery purposes (eg if you need to recreate th VM from scratch from a known state).

With the release of the vmlinuz-4.18.0-240.x and vmlinuz- 4.18.0.193.19.x kernels, ZoL cannot connect with a ZFS pool. I'm not 100% sure, but I believe the last CentOS 8 kernel to work with ZFS 0.8.5 was 4.18.0.6.x. Obviously CentOS does not support ZFS, so this means the ZoL folks must find and fix the problem.

Anthony, There are no apparent hardware problems, but as I said this machine is ancient. The hardware is a Dell T110 server (https://www.dell.com/downloads/emea/products/t110_spec_sheet.pdf) orig inally purchased circa 2010. It came with Windows Small Business Server, which I replaced with CentOS 7 when it was released in 2014. I also replaced the original Windows-only RAID card in 2014 with a Dell update that supports a 4 x 500GB Linux software RAID5. All other hardware is original, and I hate to think what the hard drive bearings must look like after more than 87,000 power-on hours. I might be able to use a C7 Live DVD with the external eSATA interface to dd the contents of the boot drive to a spare, but that might just copy a damaged LVM that still resists e2fsck. --Doc ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

A reboot fails with a file system check and drops me into maintenance mode. I tried booting from a live C7 DVD and as root running e2fsck. It complains that the superblock could not be read and suggests running "e2fsck -b 8193 ". That also fails.

The reason for this is based on the totally new repository structure Red Hat used for v8.

Upgrades for users would be a lot easier if the "upgrade" option on the install was more of an upgrade. I have seen the arguments on how Ubuntu upgrades leave unneeded packages littering the machine. However, at a minimum I would think an upgrade should keep /etc/hosts, /etc/passwd, /etc/shadow, /etc/sysconfig/network-scripts, the list if repos in use. This would at least put the machine in a usable state from the get go. Saving a list of the applications which would not be reloaded as part of the upgrade would also be useful. It would at least make it possible to get a running start at rebuilding the users environment. My issues come from the conversion of CentOS 4 and 5 to 6.

On all of them, I get no sound from firefox-78.3.0-1 and have to downgrade to firefox-68.12.0-1. I've tried with all add-ons disabled (Boy, youtube is a pain without adblock.) and there is still no sound. I don't know what else to try. I don't know what I'll do after CentOS-6 goes EOL.

[CentOS] No sound after latest Firefox update (firefox-78.3.0-1.el6.centos.x86_64)
With Firefox updated to firefox-78.3.0-1.el6.centos.x86_64, I cannot get sound from Firefox. I've tried restarting pulseaudio, also logging out and logging back in. No help. Other A/V apps work just fine. Downgrading to firefox-68.12.0-1.el6.centos.x86_64 makes sound work again. For now, I've excluded version firefox-78.3.0-1 from yum updates. Anyone else seeing this?

I *am not* using NFS, though. One thing that is key, you need to be sure your DHCP deamon is configured to give out the same IP address for both the wired Ethernet MAC and the wireles MAC.

[CentOS] ZFS fails with latest C8 kernel
As if last weekend's UEFI debacle wasn't bad enough, it now seems the latest C8 kernel (4.18.0-193.14.2) is incompatible with the current ZFSOnLinux packages (0.8.4-1). When booted to the latest kernel, ZFS is inaccessible on my C8 storage server. When I back off to the prior kernel (4.18.0-193.6.3), all is well. If a local ZFS system is unavailable to the C8 kernel support folks, I'll be happy to assist them by volunteering my system as a lab rat. --Doc Savage Fairview Heights, IL ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

I have no idea what > repos it might be in Right. Some third party repos and/or varous out-of-band "repos" use different package naming / origanizations. *Fedora* often uses "incompatable" package naming WRT RHEL/CentOS. I guess when RedHat migrates a package set from Fedora, there is sometimes package renaming and reorganization. Esp. for things like Perl, PHP, and Python packages (often these are noarch packages), so when you go back to a Fedora repo for something RedHat did not pick up, you end up with this sort of problem (been there, done that). Often the only cure is to grab the .src.rpm(s) and rebuild it(them), after manually installing the various dependencies one by one (including rebuilding them as well, as needed). Often, the low-level .src.rpms build easily enough, so it becomes mostly a bit of tedium. The OP, is probably going to have to install rpmbuild and set up a RPM Build tree. > > > -- Robert Heller -- Cell: 413-658-7953 GV: 978-633-5364 Deepwoods Software-- Custom Software Services http://www.deepsoft.com/ -- Linux Administration Services hel...@deepsoft.com -- Webhosting Services ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

Reverting to the old fashioned "rpm -qa | grep kernel-4 ; rpm -qa | grep shim ; rpm -qa | grep grub2 ; rpm -qa | grep mokutil" I get: kernel-4.18.0-147.8.1.el8_1.x86_64 kernel-4.18.0-193.14.2.el8_2.x86_64 kernel-4.18.0-193.6.3.el8_2.x86_64 grub2-tools-2.02-87.el8_2.x86_64 grub2-pc-2.02-87.el8_2.x86_64 grub2-pc-modules-2.02-87.el8_2.noarch grub2-common-2.02-87.el8_2.noarch grub2-tools-efi-2.02-87.el8_2.x86_64 grub2-tools-minimal-2.02-87.el8_2.x86_64 grub2-tools-extra-2.02-87.el8_2.x86_64 I apparently do not have either shim or mokutil packages installed. I'm not sure what this means. Am I not using EFI boot? I have local copies of the earlier v2.02-81 grub2 packages. Would it be worthwhile to replace my v2.02-87 grub2 packages, then add this line to /etc/dnf/dnf.conf: exclude=grub shim mokutil as previously advised?
