Storage Scale (formerly known as GPFS)

Shorten AFM/DR RPO Interval

The current design is that minimal RPO interval is 60 minutes. That is too long and will loss of huge data. Customer expect to set it to 1-5 minutes. 1-5 minutes RPO interval is acceptable in most of scenarios and it can help us to catch up compet...

Add option to mmlsfileset to list only independent or dependent filesets

mmlsfileset does not have a direct way to list dependedent or independent filesets. While is possible wrapping out the output of mmlsfileset -L/-Y to then pass it to mmcrsnapshot so only quiescence the IO once. I wonder if it is possible to add --...

Raise number of dependent Filesets

A customer wants to implement per directory quota. The maximum number of 10000 dependent filesets per file system is a limitation for introducing per directory quota.

when the file name is longer then 255 character it does not get copied to the SMB share, in the future version we would like to see a error message, stating the file name is too long "

when a file is not getting copied, end user dont have any clue that file has not been copied from the windows. An error message would tell them to make the file name shorter.

Use transactional write model and issue periodic disk cache flushes

GPFS (at least on Linux) does not attempt to flush the cache of the block devices to which it is writing. It relies on O_DIRECT to bypass host write cache but this does not guarantee data has been flushed to stable media. This RFE requests that GP...

CES/NFS/SMB Function Enhancements

1) CES FO/FB timeout, shorten the io pending time in the failure of CES node failure/GPFS node failure/one of FG failure in replication mode. The io pending time should be less than 4-5s. 2) AFM/DR RPO Interval, the minimal RPO interval is 60 minu...

Spectrum Scale ECE - Need quota feature to support limiting the resource usage on different storage pools

In more and more projects, we are delivering GPFS file systems with multiple storage pools for teiring. And our customers keep asking for quota limitation of each user/group/fileset on different storage pools, because different pools have differen...

Pre-occupy system resource for GPFS on nodes

Since GPFS is so critical, any standard way (from GPFS engineering or support) to configure GPFS on each node (mgmt., NSD, FPO and clients) to pre-occupy certain amount of memory and no other processes can use. I know that RHEL cgroup may be a goo...
