Эта проблема возникает на гипервизоре kvm / qemu с CentOS 7, где мы размещаем несколько виртуальных машин.
Диск / dev / sda (1918,2 ГБ) является MEGARAID LSI raid6.

Это наша конфигурация диска: sda1 - / boot, sda2 - swap, sda3 - / (root), sda4 - PV для нашего LVM с тонкой подготовкой для наших виртуальных машин.
После сбоя питания наши данные в корневом разделе были повреждены. Нам пришлось переустановить ОС, чтобы запустить сервер. Раздел / dev / sda4 мы не трогали. Перед этим мы примонтировали корневой раздел в режиме восстановления и сделали резервную копию папки / etc / lvm /.
После переустановки Centos мы попытались восстановить LVM с помощью vgcfgrestore, но получили ошибку:
[root@mia3 ~]# vgcfgrestore -f /etc/lvm/backup/vg_kvm vg_kvm -v
No devices found.

Итак, мы попытались прочитать PV и перезаписать метаданные, но безуспешно:

Все данные (корневые разделы для наших виртуальных машин) все еще там, мы проверили с помощью инструментов восстановления диска, таких как testdisk, но мы не можем восстановить lvm. Что мы делаем не так? Есть ли возможность выздоровления?
#ОБНОВИТЬ
Используя компакт-диск Centos6 и режим восстановления, мне удалось восстановить PV и VG. Однако я не могу повторно активировать пул VG и LV, мы получаем ошибку:
Executing: /usr/sbin/thin_check -q --clear-needs-check-flag /dev/mapper/vg_kvm-lvpool_tmeta
/usr/sbin/thin_check failed: 1
Check of pool vg_kvm/lvpool failed (status:1). Manual repair required!
Он работал с спасением Centos6. После восстановления загрузился в нормальный centos 7 и vg был там. Однако теперь я не могу активировать lv (тонкий пул):
[root@mia3 ~]# lvchange -ay /dev/vg_kvm/lvpool
Check of pool vg_kvm/lvpool failed (status:1). Manual repair required!
[root@mia3 ~]#
Вот команда снова с -vvv

Похоже, что Red Hat 7 и 8 имеют похожие проблемы при попытке использовать vgcfgrestore: Команда pvcreate завершается с ошибкой «Местоположение метаданных имеет недопустимую сводку для VG» . CentOS делит базу с Red Hat, так что ...
Один из ответов был: «У нас есть решение этой проблемы в восходящем направлении и в RHEL8. К сожалению, на данном этапе это слишком агрессивно, чтобы рассматривать обратный перенос на RHEL7». Другой человек, обнаруживший эту ошибку, сказал, что исправил ее, загрузив Red Hat 6, а затем vgcfgrestore работал.
Возможно, вы сможете загрузить новый компакт-диск sysrescue с USB-накопителя и сделать это?
И как я сказал в комментарии, либо сделайте резервную копию всего тома с помощью ddили хотя бы сделать что-нибудь вроде dd if=/dev/sda4 of=/somewere/backup-first100MB.img bs=1M count=100 чтобы у вас была информация о заголовке.
