Unless its has a newer BTRFS version or at least critical fixed backported, I would run away from it. Free space management in Kernel 3.0 still had issues that even with 2 GiB free the filesystem could report its full, while also denying to rm a file, delete a subvolume or do anything else to mitigate the situation. I have seen this on SLES 11 SP 3. I suggest something newer. Really. Or, if you still want to use it: If you want to store 50 GiB, keep 50 GiB of space free, or at least 20-30 GiB. I.e. have plenty of free space on the device. Do not fill up the filesystem. Or well… use another filesystem on that device. In addition meanwhile there will be a ton of other issues with such an old BTRFS fixed. So until you can´t get a newer kernel for that device, I would not use it with BRFS. -- Martin 'Helios' Steigerwald - http://www.Lichtvoll.de GPG: 03B0 0D6C 0040 0710 4AFA B82F 991B EAAC A599 84C7 -- 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
