SSD for Centos SWAP /tmp & /var/ partition
by Keith Roberts 03 Sep '25

03 Sep '25

Has anyone actually used a SSD in a Centos setup? My little experiment with a s/h WD drive for /tmp and SWAP partitions kicked the bucket on Wednesday, when the poor WD drive caught the click-of-death. It was a s/h drive to start with and lasted about 4 months. But that was without the /var/log/ partition being written to it, as I mounted that back onto /var/log from the original drive. So I had to install another (WD) drive, and repartion it and rebuild my RPM package database, from the backed-up Packages file. That seems to be all OK now. I'm wondering if it would be a good idea to use a new SSD for moving all the disk i/o to, that Linux likes to do so often. Plus putting SWAP onto a decent SSD should speed things up somewhat. Here's a short video of a laptop fitted with a SSD drive booting macOS, compared to a similar laptop booting from the standard HDD. The laptop with the SSD boots and loads some apps in 28 seconds. The other one takes twice as long. http://eshop.macsales.com/shop/SSD/OWC/Mercury_Extreme_Pro_6G/?utm_source=t… Kind Regards, Keith Roberts ----------------------------------------------------------------- Websites: http://www.karsites.net http://www.php-debuggers.net http://www.raised-from-the-dead.org.uk All email addresses are challenge-response protected with TMDA [http://tmda.net] -----------------------------------------------------------------

Problems with CentOS 8 kickstart

Hi All, I am having problems with a kickstart install of CentOS 8 When I try to do a completely automated install using PXE/UEFI it get to the point where it reads the kickstart config file. Then I see the following message "kickstart install Started cancel waiting for multipath siblings for nvme0n1" This is what I have in the kickstart file # Clear the Master Boot Record zerombr # Partition clearing information clearpart --all --initlabel autopart --nohome --type=lvm --fstype=xfs ================ When I install from a USB drive it works OK and I have the following in /dev/disk/by-id lrwxrwxrwx. 1 root root 13 Jul 5 10:28 nvme-SAMSUNG_MZVL2512HCJQ-00BL7_S64KNE0R161810 -> ../../nvme0n1 lrwxrwxrwx. 1 root root 13 Jul 5 10:28 nvme-eui.002538b11102f46d -> ../../nvme0n1 lrwxrwxrwx. 1 root root 15 Jul 5 10:28 wwn-eui.002538b11102f46d-part3 -> ../../nvme0n1p3 lrwxrwxrwx. 1 root root 15 Jul 5 10:28 nvme-SAMSUNG_MZVL2512HCJQ-00BL7_S64KNE0R161810-part3 -> ../../nvme0n1p3 lrwxrwxrwx. 1 root root 15 Jul 5 10:28 nvme-eui.002538b11102f46d-part3 -> ../../nvme0n1p3 lrwxrwxrwx. 1 root root 15 Jul 5 10:28 lvm-pv-uuid-5Dg4mg-saHa-hJJ6-n5a8-MxBS-gdFi-5jPoNn -> ../../nvme0n1p3 lrwxrwxrwx. 1 root root 15 Jul 5 10:28 wwn-eui.002538b11102f46d-part2 UNG_MZVL2512HCJQ-0-> ../../nvme0n1p2 lrwxrwxrwx. 1 root root 15 Jul 5 10:28 nvme-SAMSUNG_MZVL2512HCJQ-00BL7_S64KNE0R161810-part2 -> ../../nvme0n1p2 lrwxrwxrwx. 1 root root 15 Jul 5 10:28 nvme-eui.002538b11102f46d-part2 -> ../../nvme0n1p2 drwxr-xr-x. 2 root root 400 Jul 5 10:28 . lrwxrwxrwx. 1 root root 15 Jul 5 10:28 wwn-eui.002538b11102f46d-part1 -> ../../nvme0n1p1 lrwxrwxrwx. 1 root root 15 Jul 5 10:28 nvme-SAMSUNG_MZVL2512HCJQ-00BL7_S64KNE0R161810-part1 -> ../../nvme0n1p1 lrwxrwxrwx. 1 root root 15 Jul 5 10:28 nvme-eui.002538b11102f46d-part1 -> ../../nvme0n1p1 lrwxrwxrwx. 1 root root 10 Jul 5 11:07 dm-uuid-LVM-qQok4M7AOo1TxZZ42GwZcbuVNBs0hnkKtEdtLjwJQyIdxJcSvPv8TEAjwYGMv6yU -> ../../dm-0 lrwxrwxrwx. 1 root root 10 Jul 5 11:07 dm-uuid-LVM-qQok4M7AOo1TxZZ42GwZcbuVNBs0hnkKAooqrczySYJyiHvUAUji9oScPN2cVi7J -> ../../dm-1 lrwxrwxrwx. 1 root root 10 Jul 5 11:07 dm-name-cs_uews027-swap -> ../../dm-1 lrwxrwxrwx. 1 root root 10 Jul 5 11:07 dm-name-cs_uews027-root -> ../../dm-0 lrwxrwxrwx. 1 root root 10 Jul 5 11:07 dm-uuid-LVM-qQok4M7AOo1TxZZ42GwZcbuVNBs0hnkK5HZXbR2ow5xKGuD7jVe4UPzZm2qRLLXI -> ../../dm-2 lrwxrwxrwx. 1 root root 10 Jul 5 11:07 dm-name-cs_uews027-home -> ../../dm-2 It's looks like that I am not doing the disk drive stuff in the config file correctly. -- Gerard Hooton.

Issues booting centos7 [dracut is failing to enable centos/root, centos/swap LVs]
by Yannis Milios 01 Feb '25

01 Feb '25

Hello, I'm having a strange problem booting a new centos7 installation. Below some background on this. [I have attached the tech details at the bottom of this message] I started a new CentOS7 installation on a VM, so far all good, o/s boots fine. Then I decided to increase VM disk size (initially was 10G) to 13G. Powered off the VM, increased the vhd via the hypervisor, booted from CentOS livecd, selected "recover my centos installation". Then I used the following sequence of commands to make the new vhd size "visible" to the o/s ... - ran fdisk /dev/sda and deleted partition 2. (This is the LVM partition where the o/s is stored. The first partition is /boot [xfs] partition *non lvm*.) - created a new partition with same starting sector as before deleting it, but a different ending sector (to reflect to the increased space). - set partition type to 8e (lvm), saved settings and exit. - ran pvresize and lvresize to make new space visible to the o/s.All good, I can see the space increase on 'lvdisplay centos/root'. - ran 'mount /dev/mapper/centos-root /mnt/root' to temporarily mount the o/s partition. - ran 'xfs_growfs /mnt/root' to resize the o/s fs to the new size. It was successful and I could actually chroot to the o/s and verify new disk size. - rebooted and tried to boot from hdd this time. Grub menu shows up and loads default kernel (3.10.0-862.9.1.el7.x86_64). - after initial kernel boot up process, booting continues to initrd and then it's where the problem starts... - looks like dracut has issues locating/enabling /dev/mapper/centos-root (lv) and as a result it cannot boot to the 'real' root fs (/). - while in dracut shell, I execute the following command sequence: 1. lvm lvchange -ay /dev/centos/root 2. lvm lvchange -ay /dev/centos/swap 3. ln -s /dev/mapper/centos-root /dev/root 4. exit ...and the o/s boots fine...so looks like the pv,vg,lv is detected properly while in initrd, but somehow dracut has difficulties enabling the root,swap LVs ? - While in o/s, I rebuild initrd by using: 'dracut -f -v -a lvm' Note, I have to use '-a lvm' as for some reason, if don't, the lvm utils (lvm,lvm_scan) are not being included to the initrd, not sure why this happens. After rebooting, same thing happens, I have to manually boot the system via dracut shell. I'm a bit stuck at this point, any clues what I'm doing wrong in here ? As I previously said, this is a new installation, so I could simply reinstall the whole thing, but I would rather try to find out some answer to why is this happening ... :-) [curiosity] Some additional details: ================== I've attached /run/initramfs/rdsosreport.txt file [generated while in inird] here: https://privatebin.net/?fdc4052c0c402884#gdB/QYR3IeR55SxUbjfrkZPQfJ7jMxiUxq… o/s ver=CentOS Linux release 7.5.1804 (Core) [root@localhost ~]# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 13G 0 disk ├─sda1 8:1 0 500M 0 part /boot └─sda2 8:2 0 12.5G 0 part ├─centos-root 253:0 0 11.5G 0 lvm / └─centos-swap 253:1 0 1G 0 lvm [SWAP] [root@localhost ~]# cat /etc/default/grub GRUB_TIMEOUT=5 GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)" GRUB_DEFAULT=saved GRUB_DISABLE_SUBMENU=true GRUB_TERMINAL_OUTPUT="console" GRUB_CMDLINE_LINUX="rd.lvm.lv=centos/root rd.lvm.lv=centos/swap rd.shell rhgb" GRUB_DISABLE_RECOVERY="true"

Installing mdadm and C7 on new computer
by H 19 Oct '22

19 Oct '22

I have a new computer with 2 x 2TB SSDs where I wanted to install C7 and use mdadm for RAID1 configuration and encrypting the /home partition. On the net I found https://tuxfixer.com/centos-7-installation-with-lvm-raid-1-mirroring/ which I adopted slightly with respect to partition sizes, using RAID1 for /boot and /root as well and added the /home partition with RAID1 and chose to have /home encrypted. Is there an "official/recommended/suggested" page for installing C7 and using mdadm for RAID1 in combination with LUKS encryption? As far as I can tell things seem right but would like to check before proceeding to install lots of other software. Thanks.

OT:: Multiple PHP versions
by TE Dukes 22 Aug '22

22 Aug '22

Hello, Been trying to get multiple versions of PHP on a CentOS 7 machine, off and on for the past couple months. I have followed 5 or 6 different howtos but none work. They are very similar and they seems to be done on a fresh install as most do an apache install is the steps. I setup two virtualhosts one for PHP5.6 and one for PHP 7.4. When I create a file with phpinfo, it reports back 5.6.xxx on both sites. So, I'm wondering if I need to remove the existing PHP version that is included with CentOS? Any suggestions or a better way to do this? TIA

Make copy of CentOS 7
by Jerry Geis 20 Aug '22

20 Aug '22

I have a software raid 1 (2 disks) of CentOS 7 I want to make a working "copy" of this setup to another disk of the same size to another SSD and have it be bootable etc... Then edit something to turn off the RAID part as its only 1 disk. Or Run with the 1 disk and it will just think the second disk is failed. so can I just do "dd if=/dev/sda of=/dev/sdd" and that is all ? Put that disk in another machine and it runs? where sda is the first raid disk, sdb is second raid disk, sdc is something else not related and sdd would be where the disk loads as USB. Thanks, Jerry

php 7.4 on C7
by H 12 Aug '22

12 Aug '22

I have a C7 server running Apache and php 7.0 and 7.2 simultaneously serving websites, both installed from SCL if I remember correctly. I now have a need to install a webapp requiring php 7.4 which seems to be available only from Remi's repository and IUS. Bearing in mind I do need to continue to serve the php 7.0 and 7.2 webapps using Apache, is there a reason to prefer Remi's repository over IUS or vice versa? Anything in particular to bear in mind installing from one of them and not damaging the current setup? Thanks.
