Problems with CentOS 8 kickstart
by Hooton, Gerard 23 Jun '25

23 Jun '25

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.

I asked about SMB on Centos 6. shimi answered: >samba-swat is installed, fine, but was the service actually started? You >have not shown proof of that > >If it does, > >netstat -pltn > >Will tell you about listening ports (in case you got the networking wrong) As NMAP already indicated, port 901 is not open. It is not listed in the netstat output, either. But why not? -- Dave Close, Compata, Irvine CA +1 714 434 7359 dave(a)compata.com dhclose(a)alumni.caltech.edu "If every conceivable precaution is taken at first, one is often too discouraged to proceed at all." -- Archer John Porter Martin

Samba on Centos 6
by Dave Close 05 Jun '25

05 Jun '25

Sorry to address such an old and obsolete system. A customer is migrating up from Centos 6 but needs to keep it working a little while longer. The issue now is that Windows users are unable to map a drive letter to a Centos directory. When they go to map the drive (to "\\ip\public"), Windows says the connection is rejected, with no further details. I presume some configuration is set wrong but I haven't been able to find it after reading man pages and Google stuff. Samba is installed and so is samba-swat. But I can't get port 901 open so I can verify proper configuration of SMB. Relevant lines in current files: /etc/services: swat 901/tcp smpnameres # Samba Web Administration Tool /etc/samba/smb.conf: [/public] path = /public public = yes writable = yes printable = yes write list = +users iptables -L: -A INPUT -p tcp -m tcp --dport 901 -j ACCEPT But: $ nmap -sT -p901 localhost PORT STATE SERVICE 901/tcp closed samba-swat Please tell me what I've missed or give a pointer to better help. -- Dave Close, Compata, Irvine CA +1 714 434 7359 dave(a)compata.com dhclose(a)alumni.caltech.edu "Moral indignation is jealousy with a halo." -- H.G.

I asked about SMB access to Centos 6. Pete Geenhuizen answered: >The solution for me has always been to install wsdd and as soon as it's >running windows can almost immediately see the host, and BTW you'll need >to install it on any upgrade that you install. Thanks. But YUM tells me no such package.

cryptsetup luks
by lejeczek 17 May '25

17 May '25

Hi guys. Is this a misbehavior of some sorts? I encrypt: -> $ systemd-cryptenroll --tpm2-device=auto --tpm2-pcrs=0+7 /dev/nvme0n1p3 but unless there is only one keyslot (my even have any ID) or perhaps if it was first - but have not tired it - then 'cryptset' does not open the device @boot. From what I understand 'cryptsetup' tires all keyslots - no matter TPM provider/device is absent - I was thinking of 'timeout' but cryptsetup does not report any such issues, simply boot stops, waiting for a passphrase. I other words: it seems I need to remove all keyslots, old ones, enrolled in the past for which TPMs do not exists any more, except for the one I know is valid, only then system boots with TPM, no passphrase prompt. any thoughts much appreciated. many thanks, L.

module from repos
by lejeczek 10 May '25

10 May '25

Hi guys. 'modules' are no longer, in 'dnf'? I get none. Is there some 'changelog' on v. 10 - where important changes are covered? I searched but failed to find any. thanks, L.
