Subject:mysql 5.5.24/27 massive slow down since upgrade to solaris 10 u9 with 147440-19
View as plain text  
Hello

For nearly 3 years, we have had a master - slaves configuration working
like a charm, the slaves would be able to sync daily ... since a recent
upgrade from Solaris10u6 to solaris 10 u9 with the latest CPU bundle
(kernel patch 147440-19) on one of the two slaves, the slave upgrade cannot
keep up anymore... it is now at over 2 days behind in replication and the
delay increases... the volume of data did not increase and the second slave
seems in good shape (still on u6). No configuration change was done to the
mysql configuration itself... Is there a well know issue/parameter to
configure with the more recent versions of solaris ? The storage is on an
Hitachi  san storage with 4Gig HBAs and the volume of data to replicate is
about 6-8 1G binary log files a day... Another change is that the new
machine global zone is using zfs for the boot disks, but the database zone
itself including the data directory is sitting on ufs filesystems...
Regards
