Consistency Check: Check consistency. A check consistency determines the integrity of a virtual disk's redundant data. When necessary, this feature rebuilds the redundant information. Source: http://support.dell.com/support/edocs/software/svradmin/6.2/en/OMSS/cntrls.htm#wp681476
the remapping of bad sectors should be run automatically if the sector can't be written and the controller try to write or read from it. Please check all times the controller log if you got filesystem erros like you described. Check the log for Bad LBA's on the disk like searching the log file with "bad" Check the Count of the LBA's and check if it occurs on multiple disks like a punctured stripe.... The log you can get per megacli or open manage: Server Administrator cli: omconfig storage controller action=exportlog controller=0 where controller 0 = id of the involved controller Megacli: Megacli -FwTermLog -Dsply -a0 > log.txt - where a0 = controller 0 Best Regards/ Mit freundlichen Grüßen ____________________________________________ Patrick Fischer Senior Server Analyst Dell | Global Support Services Dell Halle GmbH in Vertretung für Dell GmbH Raffineriestraße 28, 06112 Halle (Saale), Germany Germany: +49 69 9792 4299 Austria: +43 820 240 58 256 mailto:[email protected], www.dell.de Geschäftsführer: Barbara Wittmann, Michael Kenney Vorsitzender des Aufsichtsrates: Jürgen Renz Eingetragen beim Amtsgericht Stendal unter HRB 215298, USt.-ID: DE242553389 WEEE-Reg.Nr. der Dell GmbH: DE 49515708 Online support - Antworten zu technischen Fragen, Treiber oder Anwendungsprogramme für ihr(e) System(e) http://support.euro.dell.com/support/index.aspx Service call status - Abfrage zum Servicestatus ihres(r) System(e) http://support.euro.dell.com/support/topics/topic.aspx/emea/shared/support/support_history/de/search Dell Technical Updates - Empfang zur Mitteilung von kritischen Updates, Updates für Anwendungsprogramme, Treiber und Tools für ihr(e) System(e). http://support.euro.dell.com/support/notifications/managesubscriptions.aspx -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Tim Small Sent: Saturday, May 01, 2010 12:17 PM To: Adam Nielsen Cc: linux-poweredge-Lists Subject: Re: how to get rid of bad blocks in a file on PERC 5/I?
