Re: kernel oops -> no mount (different problem than others)
Thanks for your help, but unfortunately, it wouldn't mount read-only, either. If you can think of anything else I could try, it would be greatly appreciated!

Re: kernel oops -> no mount (different problem than others)
You might try mounting it "-o ro" as a stopgap to regain readonly access. Judging from the bootlog, the error itself appears to be enospc. In which case there's no already-available quick fix; I expect a developer to chime in any second now :p > From the logs it is listing a transid error but NOT that it is > expecting a different one, simply > > device label 1TB devid 1 transid 248472 /dev/sdb That particular line is the normal listing of devices, which is expected and completely normal. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
kernel oops -> no mount (different problem than others)
Hi. I''ve been using btrfs on an external drive for >1yr but now I cannot mount it. >From the logs it is listing a transid error but NOT that it is expecting a different one, simply device label 1TB devid 1 transid 248472 /dev/sdb I've been having this problem now for more than 1 month and have not managed to get anywhere with it. Any help would be appreciated. Attached is the (edited) boot log. On Fedora 15 w/ updates-testing enabled.
