Hi Yeep, >If ACLs and other EAs migration from non scale is not supported by AFM, is there any 3rd party tool that could complement that when paired with AFM?
rsync can be used to just fix metadata like ACLs and EAs. AFM does not revalidate the files with source system if rsync changes the ACLs on them. So ACLs can only be fixed after or during the cutover. ACL inheritance may be used by setting on ACLs on required parent dirs upfront if this option is sufficient, there was an user who migrated to scale using this method. ~Venkat (vpuvv...@in.ibm.com) From: "T.A.

Sent by: gpfsug-discuss-boun...@spectrumscale.org Have you considered using the AFM feature of Spectrum Scale? I doubt it will provide any speed improvement but it would allow for data to be accessed as it was being migrated.

Date: Mon, Nov 16, 2020 2:44 PM Hi all, i have got a case where a customer wants 700TB migrated from isilon to Scale and the only way for him is exporting the same directory on NFS from two different nodes... as of now we are using multiple rsync processes on different parts of folders within the main directory. this is really slow and will take forever.. right now 14 rsync processes spread across 3 nodes fetching from 2.. does anyone know of a way to speed it up? right now we see from 1Gbit to 3Gbit if we are lucky(total bandwidth) and there is a total of 30Gbit from scale nodes and 20Gbits from isilon so we should be able to reach just under 20Gbit... if anyone have any ideas they are welcome!
