Sadly GPFS still doesn’t support flock(2), so I still avoid it.
- quotemstr 1y agoDoesn't it? https://sambaxp.org/archive-data-samba/sxp09/SambaXP2009-DATA/Henning_Henkel.pdf https://sambaxp.org/archive-data-samba/sxp09/SambaXP2009-DAT... It would be weird, even for AIX, to support POSIX byte range locks and not the much simpler flock.
- denotational 1y agoIt doesn't, at least on the version I have access to, as it is configured on that cluster. I’m using Linux rather than AIX. fcntl(2) locks are supported (as long as they aren't OFD), but flock(2) locks don't work across nodes.
