rsync of a reflink from OCFS2
...locally. The source of that new file can be a combination of parts of the existing file and parts of the remote file but it still writes the whole thing. --inplace helps with that somewhat but you will probably still write all of the file after the first difference.

rsync of a reflink from OCFS2
--no-whole-file would only make it even worse. It would have to read the remote file over the network in order to do the diff then it would write the whole file over the network anyway (--inplace would help a little). Local copies force --whole-file for a good reason. On 03/14/2018 10:05 AM, Ben RUBSON via rsync wrote: > On 14 Mar 2018, Lentes, Bernd via rsync wrote: > >> ----- On

rsync rewrites all blocks of large files although it uses delta transfer
Hi All, For a backup purpose I'm trying to transfer only the changed blocks of large files. Thus I've run "rsync" with the appropriate options: RSYNC_BKPDIR=`mktemp -d` rsync \ --archive \ --no-whole-file \ --inplace \ --backup \ --backup-dir="$RSYNC_BKPDIR" \ --verbose \ --stats \ /var/backups/mysql-dbs/. \ /mnt/bkp/var/backups/mysql-dbs/.

Hi! I am having a few problems with coxph function, I had the same problem with the use of survfit. Here it is: when calling 'M22<-coxphw(Surv(V1,V2,V4)~V5, data=XTDV, id=XTDV$V3, * prentice*= ~V5, robust=TRUE, censcorr=TRUE)' knowning that my data is: > XTDV[1:10,1:3] V1 V2 V3 V4 V5 1 0 36.39706 36 1 343.2224 2 0 36.39706 943 0 161.5931 3 0 36.39706
