Been hit by this too :( The reason for the new 'Subject' is my hope to make it easier locatable, as it is reported like this: ,---- | From: mdadm monitoring <[EMAIL PROTECTED](hostname)> | To: [EMAIL PROTECTED](hostname) | Subject: DegradedArray event on /dev/md0:hostname | | This is an automatically generated mail message from mdadm | running on hadrian | | A DegradedArray event had been detected on md device /dev/md0. | | Faithfully yours, etc. `---- Rebuilding the initrd.img seems to be the write thing to do. Just for the record. The cause of the problem is hidden in a script (in the initrd root directory) called ... 'script' :) If the initrd.img is created while a degraded array exists, the 'script' may look something similar to this: ,---- | ROOT=/dev/md0 | unload_unused_ide 'yes' pdc202xx_new adma100 aec62xx alim15x3 amd74xx \ | atiixp cmd640 cmd64x cs5530 cy82c693 generic hpt34x hpt366 ns87415 \ | opti621 pdc202xx_old piix rz1000 sc1200 serverworks siimage sis5513 \ | slc90e66 triflex trm290 via82cxxx | mdadm -A /dev/md0 -R -u 1c00514f:554404fb:14e5ac81:ce0394b0 /dev/hde1 `---- If the initrd.img is created tha same array synchronized exists, the 'script' may look something similar to this: ,---- | ROOT=/dev/md0 | unload_unused_ide 'yes' pdc202xx_new adma100 aec62xx alim15x3 amd74xx \ | atiixp cmd640 cmd64x cs5530 cy82c693 generic hpt34x hpt366 ns87415 \ | opti621 pdc202xx_old piix rz1000 sc1200 serverworks siimage sis5513 \ | slc90e66 triflex trm290 via82cxxx | mdadm -A /dev/md0 -R -u 1c00514f:554404fb:14e5ac81:ce0394b0 \ | /dev/hde1 /dev/hdf1 `---- Cheers, Cristian -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
