-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Moin, this weekend a ssd disk got an problem. No Problem, I thought... but real word acts sometime other the you think :) 1. Szenario I got an media Error on a ssd disk. So, I think trimming the whole device may work. Mounting the btrfs in rw is not possible anymore. Because the system is going to write on damaged blocks. Mounting ro is possible. So I tried to mount -o ro,subvol=/ /dev/sdl1 /mnt -> worked. The Try to send the ro-mounted subvol "rootfs", which I want to recover did not work: btrfs send -f /srv/backup/rootfs.btrfs rootfs ERROR: /mnt/rootfs is not read-only The try to change the ro-flag btrfs prop set rootfs ro true ERROR: failed to set flags for rootfs. Read-only file system was impossible. I think this is an Bug in btrfs send, not to check if an btrfs filesystem is mounted ro for refusing working. It may be much more easier to recover damaged systems, if such annoying thngs would not occour. mit freundlichen Grüßen Jürgen Sauer - -- Jürgen Sauer - automatiX GmbH, +49-4209-4699, juergen.sauer@xxxxxxxxxxxx Geschäftsführer: Jürgen Sauer, Gerichtstand: Amtsgericht Walsrode • HRB 120986 Ust-Id: DE191468481 • St.Nr.: 36/211/08000 GPG Public Key zur Signaturprüfung: http://www.automatix.de/juergen_sauer_publickey.gpg -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iEYEARECAAYFAlTGMCEACgkQW7UKI9EqarG8QwCgu80ihnBxKrnjy4rzzbrz6Riu wS0AoIEiNicS/6Zz12ct7T4fZncW5xsP =3PPi -----END PGP SIGNATURE----- -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
