Re: ISO 2020 cant mount arch-chroot

The message seems quite self explanatory no? Is the disk actually mounted and did you pacstrap the base system? Which instructions are you following?

Re: ISO 2020 cant mount arch-chroot

I can't mount disk

mount  /dev/sda1 /mnt
mount: /mnt: unknown filesystem type 'LVM2_member'.

How to fix it ? Debian was on this disc. I didn't repartition the disk, just reformatted

fdisk -l

Disk /dev/sda: 74.53 GiB, 80026361856 bytes, 156301488 sectors
Disk model: WDC WD800JD-00MS
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0xd88f769a

Device     Boot     Start       End   Sectors  Size Id Type
/dev/sda1  *         2048 152143871 152141824 72.5G 83 Linux
/dev/sda2       152145918 156301311   4155394    2G  5 Extended
/dev/sda5       152145920 156301311   4155392    2G 82 Linux swap / Solaris
GPT PMBR size mismatch (1497751 != 1986557) will be corrected by write.
The backup GPT table is not on the end of the device.

Re: ISO 2020 cant mount arch-chroot

First, backup your personal data to somewhere else, and make sure you make the backup right.

Second, follow the official installation guide: https://wiki.archlinux.org/index.php/Installation_guide

Third, before the partitioning, use “wipefs -a” to clear that mess if you don’t know how it ended up like that nor what to do with it.

Remember, keep your backup safe.

...

For the “weird” can’t mount, it’s LVM, the wiki: https://wiki.archlinux.org/index.php/LVM

Now that I said the obvious that you must have done until now, post the output of “lsblk”, use a pastebin client.
https://wiki.archlinux.org/index.php/Li … in_clients

If you have a more confortable way of doing so then go on, but I assumed that you have the live system and a cellphone...

Side note: before posting a wall of text, use
[ code ]
[ / code ]
tags, without the spaces and the content In between.
