Hello,
I'm looking for feedback on how folks are managing their crash space on
servers with large memory footprints.
I have a server with 64GB of RAM and I have provisioned a 32GB swap
partition which should suffice for holding a crash dump (assuming 3:1
compression), however when it comes to /var/crash on the file system, should
I also reserve 32GB just for a savecore operations. This would normally be
OK, but the system disks are only 72GB, and I normally allocate 12G for /
and 12G for /var and on this server 32GB for swap. I don't have enough disk
space left to accomodate a /var/crash filesystem big enough to hold a
potential crash file from a server with this much memory. These are SAS
drives as well which means that there is currently nothing larger than 72GB
available.
The server currently has 64GB of memory, but has the capcity for 256GB
(when the 4GB DIMMS become available), which makes this an even more or a
conundrum. How would one deal with this? Provision space off a SAN just for
savecore to write to? Doesn't seem right.
Anyway, any thoughts, comments, and/or suggestions appreciated.
Regards,
Peter
