Мда... Автор перешел с самодельных скриптов на автотулзовские. Я вроде как все подпорки поставил, но в одном месте рука дрогнула, а я был слишком уставшим, чтобы заметить. :( 7.1.4-alt1 (свежая версия) с исправлением уже собрался для Сизифа. Прошу втянуть ее в бранч. Изменения в этой версии: This version of sysstat adds a new command (pidstat) aimed at reporting statistics for Linux tasks (processes). This command will replace sar's options -x and -X and will have many more features (e.g. I plan to add per-process I/O statistics in next sysstat release). Another change in this version which is worth being noted is the addition of option -N to iostat. This option enables the user to query any device-mapper devices for their registered device name. It should prove useful for viewing LVM2 statistics.
Спасибо! Я тоже заметил в изрядно уставшем состоянии -- не выровнял вовремя raid5 по границе страйпа, вторые сутки развлекаюсь в онлайновое перетаскивание под огнём качающих. :)
