I thought I was being smart: rsync --inplace --copy-devices --partial --compress --progress ... Turns out I need: rsync --write-devices ... Which is not in RHEL6, so off to patch from https://git.samba.org/?p=rsync-patches.git;a=blob;f=write-devices.diff > > There is a patch to rsync for copying devices nodes - but the > /dev/... > pathnames are often symlinks. Rsync to /dev/dm-2 has the same issue: if (statret == 0 && !S_ISREG(sx.st.st_mode)) { if (delete_item(fname, sx.st.st_mode, del_opts | DEL_FOR_FILE) != 0) ... The above patch changes it to: if (statret == 0 && !(S_ISREG(sx.st.st_mode) || (write_devices && IS_DEVICE(sx.st.st_mode)))) { ... > There are utilities for copying block devices with rsync protocol - I > have a python script that I have used around somewhere, but I > can't put > my fingers on it at the moment. Thanks! Here is the RHEL6 rsync srpm (patch) and results, for all the others and Google. https://bugzilla.redhat.com/show_bug.cgi?id=1193654 -Jason _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
