Storage Scale (formerly known as GPFS)

Showing 500

extend number of independent filesets

For a file system used in a large research facility with a capacity beyond 20 PB, we would like to generate at least 5000 independent filesets for projects being active in processing and generating data. We expect initially a demand for 5000 indep...

Reflink/ficlone support

reflink/ficlone is a system call for making clones of files, where all data blocks is initially shared, and changes are then done through copy-on-write/redirect-on-write. This can be done through "cp --reflink", or IOCTL_FICLONERANGE system call. ...

Add Support for Hardware Load Balancers like the F5

We are a large bank and a large enterprise customer. Not all Open-Source software is supported. HA-Proxy is one of those not supported. But we still need to Load balance the GPFS GUI. This is a requirement when hosting Scale in OCP. We need to pla...

Subnets Config Parameter in CNSA / Remote Cluster

With MROT capability on Scale/Scale System (ESS) for Ethernet networks, the ability to use that vs. Network Bonds in OCP environments would be beneficial. In a recent lab test using an ESS3500 + OpenShift (Fusion), MROT was used initially, however...

Request to add "all" option to put filesystem in maintenance mode

In order to shutdown/startup gpfs gracefully, it is recommended to put filesystem in maintenance mode using "mmchfs --maintenance-mode" cmd before shutdown. However, this command allow only one filesystem at a time. So if the customer has many fil...

Requests and limits for statefullset ibm-spectrum-scale-gui in Spectrum Scale container native shoud be configurable

Currently CPU request for gui pods is set to 500m. This request is too large for small clusters and pod typically use ~10m. This can prevent other workload to be sheduled and it's wastefull especially in small multicluster scenarios.

CNSA / CSI add support for Access Mode ROX (ReadOnlyMany)

There are UseCases where Data should be shared between PODs or among different Clusters. To protect Data and prevent inconsistency it would be beneficial to enforce a ReadOnly Mode at OpenShift PV Level. Currently, ReadOnly can only be set in the ...

mmrestripefs % complete metric is near useless

Current behavior------------------mmrestripefs (and mmdeldisk) displays a % complete metric while it is going. Unforunately, this seems to be tracking the % of the inode of the whole filesystem that it is currently working on. Deficiency of this--...

Limit NFS Exports to a CES Group

Following limitation for NFS exports is in place (see A8.9 in Q&A section Spectrum Scale 5.1.2): If a file system that was previously exported successfully by NFS on a CES node becomes unavailable, the NFS daemon exits and the CES node becomes...
