Problem
Upon reboot the following errors appear: open(/dev/zero): Too many open files
Error
WARNING: forceload of drv/pln failed
WARNING: forceload of drv/soc failed
VxVM starting in boot mode...
open(/dev/zero): Too many open files

Solution
This is a file descriptor limit problem. The workaround is to increase the file descriptor from a default 64 to 256, 512 or maximum 1024.
To find current setting, do ulimit -a
- # ulimit -a
time(seconds) unlimited
file(blocks) unlimited
data(kbytes) unlimited
stack(kbytes) 8192
coredump(blocks) unlimited
nofiles(descriptors) 64
memory(kbytes) unlimited
#
To change settings to e.g. 512, insert the following line in /etc/system before the vxvm_START session and reboot.
- set rlim_fd_cur=0x200
- # ulimit -a
time(seconds) unlimited
file(blocks) unlimited
data(kbytes) unlimited
stack(kbytes) 8192
coredump(blocks) unlimited
nofiles(descriptors) 512
memory(kbytes) unlimited
