ok, from bitrot code I figured out gluster using sha256 hashing algo. Now coming to the problem, during scrub run in my cluster some of my files were marked as bad in few set of nodes. I just wanted to confirm bad file. so, I have used "sha256sum" tool in Linux to manually get file hash. here is the r...

Hi, I have a file in my brick which was signed by bitrot and latter when running scrub it was marked as bad. Now, I want to verify file again manually. just to clarify my doubt how can I do this? regards Amudhan -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.gluster.org/pipermail/gluster-users/attachm...

my volume is distributed disperse volume 8+2 EC. file1 and file2 are different files lying in same brick. I am able to read the file from mount point without any issue because of EC it reads rest of the available blocks in other nodes. my question is "file1" sha256 value matches bitrot signature value but still, it is also marked as bad by scrubber daemon. why is that?

Hi Amudhan, Sorry for the late response as I was busy with other things. You are right bitrot uses sha256 for checksum. If file-1, file-2 are marked bad, the I/O should be errored out with EIO. If that is not happening, we need to look further into it. But what's the file contents of file-1 and file-2 on the replica bricks ? Are they matching ? Thanks and Regards, Kotresh HR On Mon, S...

Hi, I am trying to put together a biplot using symbols and different colours instead of text as points. Someone has previously suggested using this code: PC <- prcomp (iris[,1:4]) lambda <- PC$sdev * sqrt(nrow(PC$x)) plot (t(t(PC$x)/lambda),pch=16,col=as.numeric(iris[,5])) par (new=T) Rot <- t(t(PC$rotation)*lambda) XLIM <- c(-max(abs(Rot[,1])),max(abs(Rot[,1]))) XLIM <- XLIM+(XLIM*0.7) plot(Rot,col=4,axes=FALSE,xlim=XLIM,ylim=XLIM,pch="") arrows (rep(0,nrow(PC$rotation)),rep(0,nrow(PC$rotation)),Rot[,1],Rot[,2],col=4) text (Rot[,1:2],rownames(Rot),col=6) axis (3)...

...any one know of any encryption/decryption algorithms in R? I'm not looking for anything robust - I want some way of printing output to the screen that the user can't read immediately, but can decrypt a little later. The main thing I don't want to the user to see is a number, so (e.g.) ROT13 isn't appropriate.
