Description Tesfamariam Michael 2001-02-27 19:17:59 UTC 
When installing Florence (Wolverine) to a system with PERC2/DC, PERC3/QC, 
or PERC3/DC (megaraid driver) with large Volume size (36GB or larger), the 
installation will take over 30 minutes when it gets to formatting the 
partitions with "Formatting /XX filesystem" message where XX is the 
mounting point. On VC5, it sit "Writing inode table: 1/YYY" where YYY is 
the number of blocks. Depending on how large YYY is, the system will sit 
there but once it passes from 1/YYY to 2/YYY, it will go fairly quickly.
I believe the same thing happenes when using a SCSI controller with large 
hard drives.

Comment 2 Stephen Tweedie 2001-03-02 17:06:11 UTC 
The attached patch has just been checked in to fix scsi request merging.  It
will be in our next kernel.  Please reopen this bug if it doesn't fix your
performance problem.
