[Veritas-vx] vxtrace output

2010-09-20 Thread Carl E. Ma
Hi, We are using volume manager 5.0 on solaris 9. I have difficulty to interpret vxtrace output. What does "op" and "concurrency" stand for? ==example of output line=== 4275 START write vdev homevol01 block 5771246912 len 128 concurrency 31 pid 6134 4254 END write vdev homevol01 op 4254 block 2

"op" is short for "operation". Each line in the output of vxtrace is prefixed with a number. This "op number" tells you which other lines forms a complete trace of an I/O. Examine the output of vxtrace for all lines containing "4275" and all these lines represent one I/O. On Mon, Sep 20, 2010 at 6

I've not been able to find an understandable description of "concurrency". But, I have an example vxtrace output from a simple stripe volume with a bad stripe size: vxtrace -g S1dg1 -f /tmp/appiolab1.out -o dev,disk | pg 1 START write vdev test block 35840 len 64 concurrency 1 *pid 10931* 2 STAR

There is no VxFS for Windows. Never has been and now it looks like there never will be. On Mon, Sep 20, 2010 at 8:31 PM, lktho...@gmail.com wrote: > Does anyone know if I could replace NTFS with Veritas fs? > > ___ > Veritas-vx maillist - Veritas-vx@m
