I’m running into an odd problem in which vgcreate fails with a return value or exit code of 5. It is called from a scri= pt that calls pvcreate twice to create two PVs, then immediately calls vgcreate to create= the VG.

An exit code of 5 appears to indicate excessive numbers = of VGs. However, there are no other VGs on the system prior to this call= to vgcreate. Search engine results indicate the PV might be corrupt.&nbs= p; However, the PV was just created a few milliseconds before calling vgcreate.

When calling vgcreate immediately after calling pvcreate= , is there a need to wait for some after-effects of the pvcreate to settle out?&= nbsp; Is there some command to positively determine whether the PV is actually ready= and open for business?

Any other suggestions?

Thank you,

I am not aware of any such issue, but you can run "pvs" and find out if your newly created PV is listed in the output. > Any other suggestions? If you can create a test script that creates two PV's out of two loop mounted temporary files and re-create your bug, then someone in the dm-devel forum would surely help. Thanks, Malahal.

Exit status 5 just means "command failed": $ grep -r ECMD_FAILED ~/cvs/LVM2/lib/commands/errors.h #define ECMD_FAILED 5 > An exit code of 5 appears to indicate excessive numbers of VGs. However, = there=20 > are no other VGs on the system prior to this call to vgcreate. Search eng= ine=20 There are hundreds of possible reasons for this error: $ grep -r ECMD_FAILED ~/cvs/LVM2/ | wc -l 271 > results indicate the PV might be corrupt. However, the PV was just create= d a few=20 > milliseconds before calling vgcreate. The tools normally output a more descriptive error indicating what went wrong. If for some reason you are not getting anything helpful add more verbosity (e.g. -vvvv) to try to understand where it's failing. Regards, Bryn.
