Another simple question. How do I calculate the size of the volume from the superblock? Do I just use the two fields: u_int32_t s_blocksize_bits; /* Blocksize for this fs */ u_int32_t s_clustersize_bits; /* Clustersize for this fs */ What is the formula to use? Thanks, John

Just a quick question. What is the maximum and minimum volume sizes that OCFS2 supports? I'm working on doing a plugin for EVMS to support OCFS2. One of the functions needs that info. Thanks, John

Hi all, I created a OCFS2 volume with a block size of 4kB and a clustersize of 4kB. After I mounted the volume the first time there have been already over 600 MB in use. Then I started to copy a directory with a overall size of 1784 MB(measured on an XFS with "du"). After an hour about 4 GB(!) have been used on the OCFS2 volume so I stopped the copy. The file...

Hello Rprofessionals, The SOM-Obj works very well, when i normalize my data and the plot-function, too ! But i miss or didn't find the possibility , extract the information from the SOMplot "clusterSize" and "mean" for every cluster as quantitative information ( i.e. the DataFrame with an additional column which define the calculate clusters from SOM)? My intention - compare calculate SOM results with other unsupervised classification results ! P.S. How i have got qerror to inte...

...8_oracle_bkup0 250G 198G 53G 79% /data/orabackup While a du -sh shows that 62G is used I read Sunil Mushran's article on the reported differences between df & du and that sort of makes sense (maybe I'm missing something). The filesystem was created with a Blocksize and Clustersize of 4Kb and is mounted with the following parameters: /dev/mapper/eva_mpio_myserver07_08_oracle_bkup0 /data/orabackup ocfs2 _netdev,nointr,defaults 0 0 We have a RMAN retention policy of 3 days so backups older than that do get deleted. As a test I did a df & du of this fil...

...it will be written on the other node is very slow. Reading a file on node while it will be written on the same node is fast. In the first case the node which wants to read the file has to ask the other to downgrade the locklevel. In my opinion this is a bottleneck, if the files are big. Increasing clustersize did not really help. Is there a away to speed up the read of such a file? Is it possible to open files for reading in nolock mode (NL) instead of (PR)? Thanks for your response, Egon

A lot of code runs 'qemu-img create' or 'truncate' to create blank disk images. In the past I resisted adding an API to do this, since it essentially duplicates what you can already do using other tools (ie. qemu-img). However this does simplify calling code quite a lot since qemu-img is somewhat error-prone to use (eg: don't try to create a disk called "foo:bar")

Hello, I think I found a bug when creating graphics on a PDF device using transparency. I'm using ggplots2 like this: comp <- ggplot(data, aes(x=Problemsize, y=Fitness)) + geom_smooth(fill=alpha("blue", 0.2), aes(colour=factor(Clustersize)), size=2) Which gives me a curve for each "Clustersize" with a transparent blue "cloud" around it, indication the standard deviation. Of course, using windows you cannot see this transparent cloud, but when opening a pdf containing the plot in Adobe Acrobat all is displayed pr...
