Operating Systems Linux Red Hat Can't boot RHEL7.2 due to "Start Job is Running" Post 303018801 by hicksd8 on Friday 15th of June 2018 11:01:06 AM

Does the HP box have support for IOMMU (in the bios)?

AFAIR, if so, you either need to switch it off (in the bios) or if you are on a virtualised platform you need to inform the booting RHEL of its existence.

Kernel needs to be fed with parameters:

Code:
amd_iommo=on iommu=pt

or

Code:
intel_iommo=on iommu=pt

the latter telling it to passthrough 'pt'.

Ref:
Appendix G. Configuring a Host for PCI Passthrough - Red Hat Customer Portal

I recognize that this may not be your issue but I certainly remember the HP Proliants supporting IOMMU have no chance of booting RHEL 7.4 without tweaking.

VGCFGRESTORE(8) 					      System Manager's Manual						   VGCFGRESTORE(8)

NAME
vgcfgrestore - restore volume group descriptor area SYNOPSIS
vgcfgrestore [-d|--debug] [-f|--file <filename>] [--force] [-l[l]|--list] [-h|--help] [-M|--metadatatype 1|2] [-t|--test] [-v|--verbose] VolumeGroupName DESCRIPTION
vgcfgrestore allows you to restore the metadata of VolumeGroupName from a text backup file produced by vgcfgbackup. You can specify a backup file with --file. If no backup file is specified, the most recent one is used. Use --list for a list of the available backup and archive files of VolumeGroupName. OPTIONS
See lvm(8) for common options. -l, --list List files pertaining to VolumeGroupName List metadata backup and archive files pertaining to VolumeGroupName. May be used with the -f option. Does not restore VolumeGroupName. -f, --file filename Name of LVM metadata backup file Specifies a metadata backup or archive file to be used for restoring VolumeGroupName. Often this file has been created with vgcfgbackup. --force Necessary to restore metadata with thin pool volumes. WARNING: Use with extreme caution. Most changes to thin metadata cannot be reverted. You may lose data if you restore metadata that does not match the thin pool kernel metadata precisely. REPLACING PHYSICAL VOLUMES
vgdisplay --partial --verbose will show you the UUIDs and sizes of any PVs that are no longer present. If a PV in the VG is lost and you wish to substitute another of the same size, use pvcreate --restorefile filename --uuid uuid (plus additional arguments as appropriate) to initialise it with the same UUID as the missing PV. Repeat for all other missing PVs in the VG. Then use vgcfgrestore --file filename to restore the volume group's metadata. SEE ALSO
