[Linux-cluster] gfs_tool: Cannot allocate memory

[rhurst at bidmc.harvard.edu]

An 11-node cluster, each with 12GB RAM, whereas every node can execute these commands, except for 2 of them:

gfs_tool df /home
gfs_tool gettune /home

>From strace, it is good when:

open("/home", O_RDONLY)                 = 3
ioctl(3, 0x4723, 0x7fbffdf73c)          = 0
ioctl(3, 0x472d, 0x7fbffff760)          = 719
close(3)                                = 0

And it fails when:

open("/home", O_RDONLY)                 = 3
ioctl(3, 0x4723, 0x7fbffcdf3c)          = 0
ioctl(3, 0x472d, 0x7fbfffe300)          = -1 ENOMEM (Cannot allocate memory)

The only difference on those 2 nodes is that they have 5GB shared mem allocated for its database instance, whereas the others only have 2GB, or no instance running.  There is plenty of memory (cached) available when reporting `free -mt` on them.
