轉:做「通渠佬」，畢竟比「IT 人」好
by Tim on May.12, 2012, under 生活
做「通渠佬」，畢竟比「IT 人」好，通渠通常很暢快，雖然臭一點，但最起碼立竿見影，通就通，唔通就唔通，一兩個鐘就可以走人；另一方面，朋友們總不好意思叫你免費通渠，也不會在通渠失敗之時，叫你拆了馬桶回家再慢慢通－－眼不見為乾淨，你在家修理三十個鐘，對方隨時連一句有誠意的「多謝哂」都沒有，反過來再遇到問題，立即又詛咒你：「乜果個大學讀電腦的友仔咁渣o架，呢頭修理完果頭又壞！」即使通渠不久後又爆屎渠，大家都會怪罪於亂拋垃圾的人，至多都是怪罪於馬桶，而不會怪罪於那個不幸的通渠佬。

mdadm – mismatch_cnt is not 0 on /dev/md0
by Tim on Feb.12, 2012, under 生活
/etc/cron.weekly/99-raid-check: WARNING: mismatch_cnt is not 0 on /dev/md0
if uncounted the title's warning in weekly check. We have to do the following to repair and check the array.
echo repair >/sys/block/md0/md/sync_action
echo check >/sys/block/md0/md/sync_action
Ref: http://www.centos.org/modules/newbb/viewtopic.php?topic_id=23164&forum=37 Apparently, a non-zero number is common on RAID-1 and RAID-10 due to various (harmless?) issues like aborted writes in a swap file. So my take on all of that is, if you see it on RAID-5 or RAID-6, you should worry. But if it's on an array with memory mapped files or swap files/partitions that is RAID-1 or RAID-10, it's less of a worry.
Directadmin mail forward for 1st (master) account
by Tim on Jan.05, 2012, under Linux, 電腦
In directadmin, mail can be forwarded to other mail box / e-mail address by setting forarder.
However, the setting for master account and virtual account are different. here is the tips.
For master account:
iammaster@domains.com iammaster,somebody@yahoo.com.hk
For virtual account:
iamvirtual@starfls.com somebody@yahoo.com.hk
The different is that for virtual e-mail forwarder, a copy must be sent to the virtual account and forward another copy to the forwarder address. However master e-mail forwarder doesn’t.
