RE: Problem with ORACLEASM SCANDISKS

Hi Mark,
I tried the 2 suggestions that you gave and both ended up being hung. I used strace for each command and have attached the output in the attached zip file. If you have time and could look that would be great but if you don’t have time I do understand.

I have also sent this info the Oracle. They have also asked for an SOS report which I think is usually for Oracle Linux but I’m gonna that one too.

I feel like this is something that is going to have to be addressed with my SA but they are telling me that all looks fine from their side, so I’m hoping I can gather enough info to try and communicate my issue.

Thanks for your help!
Sallie

Hi Sallie,

I'm mostly on to AFD (ASM Filter Driver) now, so it's been a while since I ran ASMLib, and even longer since I was on RAC.

But, if 'oracleasm scandisks' doesn't work, I can think of a could of things to try:

1.) what if you do 'oracleasm scandisks /dev/sda1 /dev/sdb1 /dev/sdc1', where /dev/sda1, /dev/sdb1/ /dev/sdc1 are the newdisks you're adding? That should make it much faster, not having to scan all the disks, just the one(s) you have recently added. 2.) What if you first do a 'sudo /sbin/partprobe', then try the scandisks?

I’ve stamped the new disk just fine on node 1 but now on node 2 when I run SCANDISKS, it just hangs. I read somewhere that someone had a problem with it being slow, so I left it there over 30 minutes and it was still hung. I couldn’t CTRL-C out of it – had to just shut down my session. I have 3 RAC environments and have done this process many times with no problems.

I opened a ticket with Oracle and it was routed to the Linux group who is asking me for a CSI number that includes Linux support. I’m running RHEL7, not Oracle Linux so I don’t have a CSI. I’ve asked if I need to go to RedHat with this question, but haven’t gotten any response back from Oracle.

So I’m hoping that someone on this list might have encountered something like this and can tell me where I need to go to get help on this.
