I also tried different compression levels. Without -s it works, but since this file system contains the complete digital life of our family, I would rather not share even the file names. Any ideas on what could be done? If you need help to debug the problem with btrfs-image, please tell me what I should do. I can keep the broken file system around until an image can be created at some later time. --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAEBCgAdFiEEUimQV/rXmWU8TwiKw/FH9ZgPNTUFAlh+fbgACgkQw/FH9ZgP NTWyTA/+Ms11j0/3Ts6k0gN6/b9RXPymm815Bjz2t+OJuXpRFyuSU66Pw06sveLz I1S71O0qVpDupAZ/n5wZNg8HaErZip3uNmfuDq2sIdAv3turXfr9h9wJt7RzQ7TC HPThvK5OIt44wIxkRjsi4Jq/mPkxyanwqBezivCf4NLpPcUux7xbMvCNTsL6Fo6f 49j8GiDLrgaOeqb/0fw4w0VlSFU3yLx8mvTxGNeyOQ3RCeSIPkZr9znq5JEWpRZs v+UDadniLMWHp41j6eAikSJGk9Y2R9irsBmX7qn8FdaND2cAv0cF+cp/xpE0jj4G srYSkqSGjl4GknR1mxnLSi6Pl/g1kVTl2OxGVQ4jbyD7uzhs2Sm/uqQZZRSqP9cv E3dsD1Dj6jaUhuTd+sNjWprVlXgsC4Wlf3n7XsSE4Oi4SjPak5cQeXQ37I2XGqr1 hxMliC38SKwZHEpIfMBpIIWmSNQ4dUCDk40ATQzQtrXfODBonr4hMpZ01U2DG7Pf +ZS8EUtIlbc9pNSSozMpRcahW2ZXejTN9QdbneL9eMyPxJOmwEgsPcZ7bh2Mi7ov SzMvg0eAPl22PuZ8nV0fnbjiYYjaVzodN6AJ/GoEOGo/zK67nJF/njQdyTrmc/KQ 51fFAbuO437MUy/5vGOI/c8ZzjFwE7OnDpZwKHjrXQgynOtF1T0= =4XNT -----END PGP SIGNATURE----- --=-=-=--
