[gpfsug-discuss] FW: [EXTERNAL] FLASH: IBM Spectrum Scale (GPFS) V4.1 and 4.2 levels: network reconnect function may result in file system corruption or undetected file data corruption (2017.10.09)

[Oesterlin, Robert]

Can anyone from the Scale team comment?

Anytime I see “may result in file system corruption or undetected file data corruption” it gets my attention.
