tmpfs

I have a tmpfs mount defined in my /etc/fstab with a size of 1024m, but when I restart the server it sizes itself to 5.9G. If I run mount -o remount /dev/shm, the size will correct itself to 1G. But it'll revert the next time the server is restarted.

The entry in fstab is:

tmpfs                   /dev/shm                tmpfs   size=1024m        0 0

Could there another file that mount could be calling during startup? How might I find that file?

Hi, A friend of mine destroyed his Nvidia RAID1 array somehow and in trying to fix it, he ended up with a non-working array. Because of the RAID metadata, the actual disk data was stored at an offset from the beginning. I was able to identify this offset with dd and a hexeditor and then I used losetup… >>> More
