I am uploading the file which has the CSPOC commands and screen shots.
As you can see the it says the VOLUME GROUP is in concurrent mode and when I go and list a concurrent VGs there is nothing
cl_extendlv: VG pb0oravg is concurrent
Does anyone know where I can find good documentation on modifying AIX logical volumes. Basically, I have a box that has 2 file systems that rae 99% full. I would like to add another disk, and migrate a file system or 2 to it, then reclaim the space by adding it to other volumes. I understand that... (1 Reply)
I had just updated - reinstalled - my RH9 to a Fedore Core 3.
I did not know about the Logical volumes that automatically combined partitions on drive 1 and 2 into one mounted volume. In my attempts to do something with the hdb2 partition - not knowing that it was already in use - I killed my... (2 Replies)
I have just created two RAID 0 ( Stripped ) devices through Storage Manager and can see them as d0 and d1 ( /dev/md/dsk/d0 and d1 appear to exist )
However how do I now mount these devices ? The manual talks about creating a UFS of LOFS filesystem. Do I need to do this ?
I have create /u01... (3 Replies)
Hi Everybody,
Is there any way to know the used space on a specific Logical Volume?
Note, my question related to the LVs that have no mount point & not belong to any FileSystem.
Thanks in advance :rolleyes: (7 Replies)
hi
i am wondering if it is possible to use one nfs mount point for several logical volumes.
i have a top level directory /imaging with data1 - data50 below it. each dataX directory is a logical volume configured through LVM. if i mount them separately on the client (i.e. 50 lines in fstab... (1 Reply)
Hi all,
How do u rename a logical volume group and the logical volumes belonging to that? The logical volumes contain data and are in use.
eg: Renaming dev/vgov to dev/ov-dg ? (6 Replies)
I have a veritas file system (fsA) that is nearing capacity. We have secondary file system (fsB). that is unused and would like to move some of it's disk space but I'm unsure as to how to do this with.

Does anybody if it is possible to convert raw logical volumes to jfs2? If so how is it done or where can I find the information to make the conversion. We have an Oracle Db on AIX and it is using raw lv's which we want to convert to jfs2 because the raw devices don't restore correctly from our... (4 Replies)

Check Solaris VM Databases metadb does not have enough information about logical volumes. Current value is 0%
I have checked the SVM status, all disks are good state and synched perfectly. no errors in metadb -i.
what is this alert exact mean? what we have to check for the value?

dispatch_benchmark_f
dispatch_benchmark(3) BSD Library Functions Manual dispatch_benchmark(3)NAME
dispatch_benchmark -- Measures block execution time
SYNOPSIS
#include <dispatch/dispatch.h>
uint64_t
dispatch_benchmark(size_t count, void (^block)(void));
uint64_t
dispatch_benchmark_f(size_t count, void *context, void (*function)(void *));
DESCRIPTION
The dispatch_benchmark() function executes the given block multiple times according to the count variable and then returns the average number
of nanoseconds per execution. This function is for debugging and performance analysis work. For the best results, pass a high count value
to dispatch_benchmark(). When benchmarking concurrent code, please compare the serial version of the code against the concurrent version,
and compare the concurrent version on different classes of hardware. Please look for inflection points with various data sets and keep the
following facts in mind:
o Code bound by computational bandwidth may be inferred by proportional changes in performance as concurrency is increased.
o Code bound by memory bandwidth may be inferred by negligible changes in performance as concurrency is increased.
o Code bound by critical sections may be inferred by retrograde changes in performance as concurrency is increased.
o Intentional: locks, mutexes, and condition variables.
o Accidental: unrelated and frequently modified data on the same cache-line.
RETURN VALUE
The dispatch_benchmark() function returns the average number of nanoseconds the given block takes to execute.
