Subject: increase SD_STATS ?
Date: Fri, 19 Aug 2005 10:02:43 +0200 [thread overview]
Message-ID: <43059223.4020205@ext.bull.net> (raw)
Hi,
Due to SD_STATS=256 (/drivers/scsi/sd.c)
there's a limit on the max /dev/sd devices.
Now, we have a large FC fabric, with more than 3500 LUNs...
=> Of course, we have an Oops when an HBA is connected to the fabric
(still sd.c, BUG in function sd_iostats_bump when sd>SD_STATS)
What (bad) side-effects can be expected if we increase SD_STATS (4096 should be
nice, may be 8192) ?
Best regards.
