>Number: 2690 >Category: kern >Synopsis: When Using ccd in a mirror mode, file creation fails, >Confidential: no >Severity: serious >Priority: low >Responsible: freebsd-bugs >State: open >Class: sw-bug >Submitter-Id: current-users >Arrival-Date: Fri Feb 7 17:00:08 PST 1997 >Last-Modified: >Originator: Robert Sexton >Organization: Robert Sexton - robert@kudra.com >Release: FreeBSD 2.1.6-RELEASE i386 >Environment: 2.1-stable as of 6 Feb - 1997 SCSI-2 drives, on an adaptec 2940 controller. ccdconfig ccd0 128 6 /dev/sd0f /dev/sd2f >Description: In testing ccd for use as a disk mirroring facility, tests determined that disk failure could cause a filesystem inconsistency. For testing purposes, I set up two identical disk slices, and mirrored them with ccd. Whne I turned off the external drive, copies to the ccd device failed as expected, but I was able to unlink existing files. When I brought the external drive back on line, fsck found the unlinked files, and dutifully placed them in lost+found. CCD did not report the write failure to syslog. >How-To-Repeat: See above. >Fix: >Audit-Trail: >Unformatted: but rm works
