-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hannes touched on this briefly in his thin provisioning topic, where he'd like some sort of notification system to allow tools to automatically adjust thin provisioned storage either by extension or trimming. I'd like to extend the topic to notification for similar conditions that can occur with btrfs snapshots, especially in the case where they happen automatically. Hints from the file system when ENOSPC is approaching and automatic cleanup would be useful would help user experience quite a bit. Likewise, with LVM snapshots, file systems will encounter EIO when the CoW device runs out of exception space. A general way to communicate this information to userspace would be useful in a bunch of different scenarios. - -Jeff - -- Jeff Mahoney SUSE Labs -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.18 (Darwin) Comment: GPGTools - http://gpgtools.org iQIcBAEBAgAGBQJRIoKRAAoJEB57S2MheeWyLN4P/2obs0VYultPhyW+C9il6EKD uUpLfGlyALYKxSjBEPSTUNOWA3mlWg1TqBc459mMEitgR4pK0aM97yPsOVktGyib d0oRpmsd3K6LAwUQw4iTgq+sY+Zvc9329zUl6n0HgnwPYagUI9uZeYfG6/A+k5LR ebyn0oIG2hEemEy9AYaBHVqNotz4sBlX2UgsIuGGxfuzs7eG0EPVz0C57eRqW00+ 7AtC6rmDvNT5U17ozVuOzJGYu/4yZDhxhD4roCxFDM6NkQCa1NA4TVRDJZ9ChhqC N4wFancoqQmwm1Ra9+RQ21ErpMCfTDfIQx+ntnaFL3x2kLWla5CDhtkSWoMk9Ejk FPKVcaov1SaianCsEJS5pMCXylw3wCKhuS0TiJJ90BmLIAMP/ETo9vsnftJqbReD fd1qX/bzSJ+h9cBK/+XNUVUXia91PrAy8xHwPAB9AhaT0FCA11udpWVEy8R6C7gh vV9kgB7WCAjzI7UHXYAEDbF/whayCyTwjTqFfDbMQ98053AF0qHd+pkazcUPSRcg w85kAMGcZflBtt7bqmADLmowp+ANGKhqbYHCINSx/eeaId2WUSRAoswAsS7Gr3TB S7bjSNfJrxfLJHfM9BFqu9PyqHQrYHQxVzo9qa3dD5qEAhcPtsacO5qzcDJOSHcF Ys3admefajoNllMWcyLq =8UKB -----END PGP SIGNATURE----- -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
