Re: [CentOS] mounting XFS RAID-1 disk partition that needs repair.
I'll take a look at these two ideas soon. Thanks!

Are you sure the filesystem is really corrupt? Maybe it's only your kernel which doesn't understand the old XFS version? To use older xfs_repair, you can just download an older version like xfsprogs-2.9.4-1.el4.centos.x86_64.rpm, extract it to a directory and call the xfs_repair binary from the package. I'm not sure whether you need a matching xfs kernel module to run xfs_repair successfully. Regards, Simon ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
Re: [CentOS-es] TPM 1.2 y encriptado con luks.
Hola Orkcu, Gracias por tu respuesta. La configuración con Clevis and Tang no me va a funcionar porque de acuerdo a la documentación oficial TPM 2.0 es un requerimiento, y las computadoras que estoy usando únicamente soportan TPM 1.2 ( https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/security_hardening/configuring-automated-unlocking-of-encrypted-volumes-using-policy-based-decryption_security-hardening). Muchas gracias por compartir tu experiencia.

[CentOS] CentOS8 Docker: "repomd.xml parser error: Parse error at line" after enabling /etc/yum.repos.d/CentOS-Linux-ContinuousRelease.repo
I'm having trouble with dnf repos in a centos:8 Docker container after I enable the continuous release repo: 1. docker pull centos:8 2. docker run -it centos:8 bash -i 3. From Docker container: * dnf install -y 'dnf-command(config-manager)' && dnf config-manager --enable cr * dnf update The update results in: Failed to set locale, defaulting to C.UTF-8 CentOS Linux 8 - ContinuousRelease 43 kB/s | 8.3 kB 00:00 Error: Failed to download metadata for repo 'cr': repomd.xml parser error: Parse error at line: 66 (Opening and ending tag mismatch: meta line 0 and head ) /etc/yum.repos.d/CentOS-Linux-ContinuousRelease.repo contains: mirrorlist=http://mirrorlist.centos.org/?release=$releasever=$basearch=cr=$infra #baseurl=http://mirror.centos.org/$contentdir/$releasever/cr/$basearch/os/ If I switch these around by commenting out mirrorlist and uncommenting baseurl, it works. Is this a problem with a repo mirror? ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] mounting XFS RAID-1 disk partition that needs repair.
You could try downloading an ISO of knoppix, and boot from that with the drive installed, and use the xfs_repair tools from there without having to install other tools on the drive in question.
