Just interjecting here because I keep seeing things like this, and they're often buggy, and there's an easy answer: > DEVICE=`mount | grep /var/lib/ceph/osd/ceph-$ID| cut -f1 -d"p"` findmnt(8) is your friend, any time you want to find out about mounted filesystems, and much more reliable than grepping the output of mount or /proc/mtab/ or whatever (consider if ID is 1 and you have ceph-1 and ceph-10 mounted on the host, for example). findmnt -T "/var/lib/ceph/osd/ceph-$id" -n -o SOURCE is probably what you wanted here. Findmnt is in util-linux, and should be in all non-ancient distributions. Here ends the message from the findmnt(8) appreciation society :) Regards, Matthew -- The Wellcome Trust Sanger Institute is operated by Genome Research Limited, a charity registered in England with number 1021457 and a company registered in England with number 2742969, whose registered office is 215 Euston Road, London, NW1 2BE. _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
