Is it practical to get a R/W file handle opened against an existing file on an unmounted ext2 filesystem? -- Chuck Wolber Electronic Flight Bag Crew Information Systems/ Linux Wonk 253.576.1154 "You can't connect the dots looking forward; you can only connect them looking backwards." --Steve Jobs

As best I understand it, colSums (and associated functions) in S+ 6 are optimized functions (calling special C routines) for doing simple matrix math. For example, it seems like (in S+): all.equal(colSums(m), apply(m, 2, sum)) should be TRUE for any matrix m. It also seems like colSums (and its brethren) are very fast. My question: Are there equivalents to colSums in R? Thanks, Dave Kane

During my initial download for my home directory backup, it took rsync over 6 hours to do the initial backup, but I can FTP the stuff in about 30 Mins. Is Rsync usualy this slow? I have compression turned on, and its across a 100 MB/S network, Anyone had this problem before? Steve Sills

Hi all, I want to setup a RAID storage system, where i have two systems connected to it. the filesystems are mapped out to both connectors. I want the master host mount them read write, and the slave read only. in my fstab on the slave I have a line like the following: /dev/sdb1 /mount ext3 acl,noauto,user_xattr,nosuid,ro 0 0 so in man 5 fstab, it is written, that when the 6. field

I have an ext3 filesystem mounted r/w on 1 host and r/o on multiple hosts. Dangerous but cost effective. I recently implemented some protection through a fc switch that restricts some hosts to r/o access to the data luns. So if someone types mount -o rw or something, all is not lost. The issue occurs when it's mounted r/w on 1 host and another host attempts to mount it r/o. The mount

What I want to do is use rsync to back up a folder to an external drive. I would like to keep 30 days worth. For example: I have backups of June 1 - June 30. Once July 1 comes along, I want to keep June 2 - July 1 and delete June 1, and so forth. Any ideas how I can accomplish this? -- View this message in context: http://www.nabble.com/Rysnc-Schedule-tf4104577.html#a11672997 Sent from the

...skus, I want to develop a prediction model. I followed your paper and analysed thro' weighted coxph approach. I can develop nomogram based on the final model also. But I do not know how to do internal validation of the model and subsequently obtain calibration plot. Is it possible to use Wolbers et al Epid 2009 approach 9 (R code for internal validation and calibration) . It is possible to get these measures after using R function 'crr' or 'FGR'. That is why I wanted to go in that route. At the same time, I had this doubt because their approach assume a record per individ...

Hi all, I'm new to the rsync list. I've been searching for two days and have tried five different installs and so far none work the way I need them to.

I've been getting this error message for a few days from a customer's server and we can't seem to decipher it.

The customer side is running 2.6.3 compiled from source. #### inflate (token) returned -5 rsync error:

Have the hard-links optimizations that were described here been implemented? http://lists.samba.org/archive/rsync/2004-January/008137.html In any case, what's the general consensus behind using the --hard-links option on large (100GB and above) images?

Hi, We back up a lot of machines with varying version of rsync installed on them. The oldest machine (hopefully soon to be retired) is running rsync version 2.5.7 (protocol version 26). We back this machine up from "/" onwards with a few excludes in there. I noticed today that whenever we use the --relative and --delete flags together, the --delete flag seems to have no affect.

Just built 2.6.1 and started testing it. Nice job guys. I especially love the --progress and hardlink tweaks. Quite often, while I have systems backing up out of cron, I'd love to be able to see the --progress. Unfortunately, it's just not practical to crank up the verbosity like that on a regular basis (some of these systems have a few million files). A neat feature I'd like to see

Hi - there's a flag for rsync to compress the files in transit - is it possible to compress one side (target) with gzip and have rsync still work correctly? Any help would be appreciated. -- Ken
