Re: [Libguestfs] error invalid partition data while using libguestfs-tools

Thanks for replying, rich. here are some informations i gathered. the guest is linux (centos) and i find out the guest's file system is 'xfs' using `df -hT`: ``` $ df -hT Filesystem Type Size Used Avail Use% Mounted on /dev/mapper/centos-root xfs 8.0G 1003M 7.1G 13% / devtmpfs devtmpfs 484M 0 484M 0% /dev tmpfs tmpfs 496M 0 496M 0% /dev/shm tmpfs tmpfs 496M 6.8M 489M 2% /run tmpfs tmpfs 496M 0 496M 0% /sys/fs/cgroup /dev/vda1 xfs 1014M 132M 883M 14% /boot tmpfs tmpfs 100M 0 100M 0% /run/user/0 ``` and sgdisk version is 0.8.10: ``` $ sgdisk --version GPT fdisk (sgdisk) version 0.8.10 ``` also, i tried the command you gave. it came out the same output: ``` $ virt-rescue --ro -d 138093b9b33345c38e58efa014036bd8 ><rescue> sgdisk /dev/sdb -i 1 Invalid partition data! ```

but strange things happened when i tried some other reports' suggestions: https://listman.redhat.com/archives/libguestfs/2016-February/msg00145.html https://listman.redhat.com/archives/libguestfs/2018-November/msg00026.html i did these things: 1. set LIBGUESTFS_BACKEND to direct; 2. recompile the `libguestfs-1.40.2-10.el7.src.rpm` without the ` XXXX-RHEL-7-Reject-use-of-libguestfs-winsupport-features-.patch `; 3. run the `virt-rescue` command again. ``` $ virt-rescue --ro -d 138093b9b33345c38e58efa014036bd8 ><rescue> sgdisk /dev/sdb -i 1 Creating new GPT entries. Partition #1 does not exist. ``` and the command works somehow. apparently, i still dont understand what happened indeed. and i have read about the official explanation of LIBGUESTFS_BACKEND, is this something to do with libvirt? is it a bug or something? https://libguestfs.org/libguestfs-test-tool.1.html# trying-out-with-without-libvirt
