Subject: syncing RAID1 with more than 10MB/sec
Date: Wed, 30 Mar 2005 11:12:57 +0200 [thread overview]
Message-ID: <424A6D99.6070501@netuse.de> (raw)
Syncing a raid1 takes long time for large disks because of
the 10MB/sec limit:
Mar 30 10:58:31 imap1 kernel: raid1: raid set md2 not clean;
reconstructing mirrors
Mar 30 10:58:31 imap1 kernel: raid1: raid set md2 active with 2 out of 2
mirrors
Mar 30 10:58:31 imap1 kernel: md: syncing RAID array md2
Mar 30 10:58:31 imap1 kernel: md: minimum _guaranteed_ reconstruction
speed: 100 KB/sec/disc.
Mar 30 10:58:31 imap1 kernel: md: using maximum available idle IO
bandwith (but not more than 10000 KB/sec) for reconstruction.
Is it possible to raise this value (without recompiling)?
I know about possible performance tradeoffs with other
processes, I'm just generally interested.
Thanks.
