Here is a report on several disk configurations that was done in 2009 using benchmark code bonnie++ (32-bit 2-CPU Athlon box):
which can be found in the Debian repositories.
Currently I use RAID10 with 4 SATA disks with LVM on top of the RAID on a virtual-machine server. I have not run the bonnie++ benchmarks on that system, but perhaps I will now that I see that there is some interest.
The only reason I would use RAID10 with less than 4 disks is practice (as with setup, etc), not for performance.
I am having some troubles with apt-get. I did an apt-get update and an apt-get upgrade. Some dependencies did not download, and so I had to do `apt-get -f install` to fix that. The thing is I get an error about /var/lib/dpkg/available

Hi folks,
I am self-learning as I can
I have a script that has read a file into an array.
I can read out each line in the array with the code:
for INDEX in {0..$LENGTH} ## $LENGTH was determined at the read in
do
echo "${data}"
done
What I need to do is test the first char... (2 Replies)
Hi all,
I am looking for a quick/short way in awk to check if an associative array has any content.
I know I can split() it to an indexed array and check if the 1st element is set, or cycle through it with something like for( ele in arr ), but I want to avoid that, as I am looking for a shorter... (3 Replies)
Hi everyone,
I am trying to prevent the ehci_hcd kernel module to load at boot time.
Here's what I've tried so far:
1) Add the following line to /etc/modprobe.d/blacklist.conf (as suggested here):
2) Blacklisted the module by adding the following string to
3) Tried to blacklist the module... (0 Replies)
Hi,
another little question...
"sn" is an array whose elements can vary from about 55,000 to about 150,000 elements. Each element consists of an integer between 0-255, eg: ${sn} contain the value: 103 . For a decrypt-procedure I need scroll all the elements 4 or 5 times. Here is an example of... (15 Replies)
Hi Folks,
Could anyone please assist me with the what could be the scenarios to test the file system mount/umount performance check in HPUX.

Hello,
P7 machine
PCI Express x8 Planar 3Gb SAS Adapter
RAID10 array(2 disks)(not AIX lvm) was configured and working, then one disk failed and IBM support replaced that. Now raid array is degraded, data is not lost. I see new disk model(same as original) serial and etc.

Ya, I know, who in this day and age is mirroring rootvg...?
But yes, my shop does and I need to script checking for it.
I also know I could just inverse the the logic and call the LV mirrored
if the LPs and PPs were not equal. But I want to do the math in the if test
and also know I could... (5 Replies)

GO-TESTFLAG(7) Miscellaneous Information Manual GO-TESTFLAG(7)NAME
go - tool for managing Go source code
DESCRIPTION
The 'go test' command takes both flags that apply to 'go test' itself and flags that apply to the resulting test binary.
The test binary, called pkg.test, where pkg is the name of the directory containing the package sources, has its own flags:
-test.v
Verbose output: log all tests as they are run.
-test.run pattern
Run only those tests and examples matching the regular expression.
-test.bench pattern
Run benchmarks matching the regular expression. By default, no benchmarks run.
-test.cpuprofile cpu.out
Write a CPU profile to the specified file before exiting.
-test.memprofile mem.out
Write a memory profile to the specified file when all tests are complete.
-test.memprofilerate n
Enable more precise (and expensive) memory profiles by setting runtime.MemProfileRate. See 'godoc runtime MemProfileRate'. To pro-
file all memory allocations, use -test.memprofilerate=1 and set the environment variable GOGC=off to disable the garbage collector,
provided the test can run in the available memory without garbage collection.
-test.parallel n
Allow parallel execution of test functions that call t.Parallel. The value of this flag is the maximum number of tests to run
simultaneously; by default, it is set to the value of GOMAXPROCS.
-test.short
Tell long-running tests to shorten their run time. It is off by default but set during all.bash so that installing the Go tree can
run a sanity check but not spend time running exhaustive tests.
-test.timeout t
If a test runs longer than t, panic.
-test.benchtime n
Run enough iterations of each benchmark to take n seconds. The default is 1 second.
-test.cpu 1,2,4
Specify a list of GOMAXPROCS values for which the tests or benchmarks should be executed. The default is the current value of
GOMAXPROCS.
For convenience, each of these -test.X flags of the test binary is also available as the flag -X in 'go test' itself. Flags not listed
here are passed through unaltered. For instance, the command
go test -x -v -cpuprofile=prof.out -dir=testdata -update
will compile the test binary and then run it as
pkg.test -test.v -test.cpuprofile=prof.out -dir=testdata -update
