Description George R. Goffe 2011-12-31 12:11:24 UTC

Description of problem:

I was editing a file on this disk and it's connection to the system appears to have spontaneously dropped (see /var/log/messages snippet below). This problem was reported by several people and was fixed. Did the fix get into my current kernel? My current kernel is: 2.6.35.14-106.fc14.x86_64 but the problem has occurred on other kernels.

Version-Release number of selected component (if applicable):

fedora core 14 x86_64; Freshly installed and UP TO DATE.

How reproducible:

Frequently occurs

Steps to Reproduce:
1.attach the drive
2.mount the drive
3.start using it (does NOT appear to be I/O load dependent)
  
Actual results:

/dev/sdb1 spontaneously disconnected from the system leaving the journal recoverable and re-attached(?) itself as /dev/sdc1

Expected results:

No disconnects.

Comment 1 Fedora End Of Life 2012-08-16 13:52:44 UTC

This message is a notice that Fedora 14 is now at end of life. Fedora 
has stopped maintaining and issuing updates for Fedora 14. It is 
Fedora's policy to close all bug reports from releases that are no 
longer maintained.  At this time, all open bugs with a Fedora 'version'
of '14' have been closed as WONTFIX.

(Please note: Our normal process is to give advanced warning of this 
occurring, but we forgot to do that. A thousand apologies.)

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, feel free to reopen 
this bug and simply change the 'version' to a later Fedora version.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we were unable to fix it before Fedora 14 reached end of life. If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora, you are encouraged to click on 
"Clone This Bug" (top right of this page) and open it against that 
version of Fedora.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here:
