Hi,
I have a Linux (Debian Sarge) server with more than 4Gb of memory, I'm
running XFS on other servers for a long time without any problem. (Less or
equal to 4Gb of memory)
Actually i'm using 2.4.31 kernel, when i add PEA (64Gb of memory) in my
kernel i have a memory leak when i'm working on XFS File system.
Exemple :
---------
I have 2 volumes (/xfs1 & /xfs2) of 1TB with million of small files on
/xfs1, i trie to make a backup of file from /xfs1 to /xfs2 (tar -cvf
/xfs2/backup.tar /xfs1), after several minutes the memory is full, and i
get this messages :
-> kernel: __alloc_pages: 0-order allocation failed (gfp=0xf0/0)
-> kernel: __alloc_pages: 0-order allocation failed (gfp=0xf0/0)
-> kernel: __alloc_pages: 0-order allocation failed (gfp=0x1f0/0)
-> kernel: __alloc_pages: 0-order allocation failed (gfp=0x1f0/0)
-> kernel: __alloc_pages: 1-order allocation failed (gfp=0x1f0/0)
-> kernel: __alloc_pages: 0-order allocation failed (gfp=0xf0/0)
-> kernel: __alloc_pages: 0-order allocation failed (gfp=0x1f0/0)
-> kswapd/bdflush is using full CPU
-> Swap use = 0
If i rebuild my kernel with the "High Memory Support" to 4Go (or less)
everything is fine, backup process and system is working for many many
days without any error message.
Somebody have a solution, or i must switch to an other file system ti use
all my memory ?
Thanks,
Brice GIBOUDEAU
PS : The server with more than 4Gb of memory is an HP DL580 with 2 MSA30
and a 4 Channel Smart Array Raid Controler.
