Re: [gpfsug-discuss] How to use RHEL 7 mdadm NVMe devices with Spectrum Scale 4.2.3.10?

Hi Lance, We are doing it with beegfs (mdadm and NVMe drives in the same HW.) For GPFS have you updated the nsddevices sample script to look at the mdadm devices and put it in /var/mmfs/etc? BTW I'm interested to see how you go with that configuration. Cheers, Greg -Original

[gpfsug-discuss] How to use RHEL 7 mdadm NVMe devices with Spectrum Scale 4.2.3.10?

We have a Dell R740xd with 24 x 1TB NVMe SSDs in the internal slots. Since PERC RAID cards don't see these devices, we are using mdadm software RAID to build NSDs. We took 12 NVMe SSDs and used mdadm to create a 10 + 1 + 1 hot spare RAID 5 stripe named /dev/md101. We took the other 12 NVMe SSDs

Re: [gpfsug-discuss] GSS Software Release?

Public information on GSS updates seems nonexistent. You can find some clues if you have access to Lenovo's restricted download site . It looks like gss3.3b was released in late September. There are gss3.3b download options that include

Re: [gpfsug-discuss] GSS Software Release? (Ryan Novosielski)

Hi Ryan, As an Ex-GSS PE guy for Lenovo, a new GSS update could almost be expected every 3-4 months in a year. I would not be surprised if Lenovo GSS-DSS development started to not update the GSS solution and only focused on DSS updates. That is just my best guess from this point. I agree with

[gpfsug-discuss] Wrong behavior of mmperfmon

Hello, I'm using mmperfmon to get writing stats on NSD during a write activity on a GPFS filesystem (Lenovo system with dss-g-2.0a). I use this command: # mmperfmon query 'sf-dssio-1.psi.ch|GPFSNSDFS|RAW|gpfs_nsdfs_bytes_written' --number-buckets 48 -b 1 to get the stats. What it returns is a

Re: [gpfsug-discuss] GSS Software Release? (Ryan Novosielski)

>any idea when a newer GSS software release than 3.3a will be released? That is definitely a question only our friends at Lenovo can answer. If you don't get a response here (I'm not sure if any Lenovites are active on the list), you'll need to address it directly to Lenovo, e.g. your account

Re: [gpfsug-discuss] GSS Software Release?

AFAIK GSS/DSS are handled by Lenovo not IBM so you would need to contact them for release plans. I do not know which version of GPFS was included in GSS 3.3a but I can tell you that GPFS 3.5 is out of service and GPFS 4.1.x will be end of service in April 2019. Regards, The Spectrum Scale
