Linux-x86_64 Error: 28: No space left on device

Check the kernel parameter shmall in the /etc/sysctl.conf file.

The parameter shmall is the total shared memory in pages, that the system can use at one time.

$cat /proc/sys/kernel/shmmax

Command to check the page size,

$ getconf PAGE_SIZE

As per the Oracle,

shmall = Total_RAM/Page_Size

Change kernel.shmall = 1024 * 1024 * 1024 * RAM_Size / PAGE_Size

Edit the shmall parameter in the /etc/sysctl.conf file

For Example,

$ su – root

vi /etc/sysctl.conf file:

kernel.shmall=16777216

save the file and execute the below command to effect the changes done,

# sysctl -p
