Neil, Thank you, the last command was able to get the RAID1+0 running as needed. Unfortunately, the re-assembled disc is not functional. However, I still wonder if I have made a mistake in figuring out the proper failed disc (based on your comments) ... Therefore, I'll have to switch the discs as soon as I get back to home and check if I can get anything else from the raid-device with your incstructions (as neither of the discs are absolutely dead, one of them just hangs the machine completely sooner or later ie in 5mins or 1h). I'm also wondering, how it can be that a single IDE-disc (in this case IBM 60GXP or 75GXP don't know which one for sure) is able to halt the whole machine ... I have 6 discs connected to that server and they are all the only drives in their own channel (no slaves). Four of the drives are connected to HPT374-chip and two more to Sil680 PCI-card. I don't really expect any solution for this question, I'm more or less just wondering if anyone else has had similar problems with their hardware ? > It should assemble successfully, but I make not promises about what > sort of data will be on them. Thank you for your time Neil! Sincerely, Tomi Orava PS. I wonder if there exists any problem solving examples about real life cases in any of the docs (HOWTO, man-page etc). Perhaps it might be helpful to some one if I just gather up the mails related to this case and put them on the web for example ... even though every problem has little bit different environment & setup, but it might still help in deciding which commands to run and which ones to avoid (in order to not lose data by mistake). - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
