From mdadm man:

--examine applies to devices which are components
of an array, while --detail applies to a whole array which is currently active.
So you can --examine /dev/sdf4, for instance, not /dev/md2. And you can --detail /dev/md2, not /dev/sdf4. Smilie

Also, the system can't seem to find the volume -
vgscan -v
Wait. We were speaking about a raid volume. This is for LVM(2) volumes: completely different things.

Quote:
Code:
mount -t auto dev/md2 /mnt/raid
mount: special device dev/md2 does not exist

Do you run it from the root directory? Otherwise dev/md2 is not /dev/md2.

BIO_push(3SSL)                                                        OpenSSL                                                       BIO_push(3SSL)

NAME
BIO_push, BIO_pop - add and remove BIOs from a chain. SYNOPSIS
#include <openssl/bio.h> BIO * BIO_push(BIO *b,BIO *append); BIO * BIO_pop(BIO *b); DESCRIPTION
The BIO_push() function appends the BIO append to b, it returns b. BIO_pop() removes the BIO b from a chain and returns the next BIO in the chain, or NULL if there is no next BIO. The removed BIO then becomes a single BIO with no association with the original chain, it can thus be freed or attached to a different chain. NOTES
The names of these functions are perhaps a little misleading. BIO_push() joins two BIO chains whereas BIO_pop() deletes a single BIO from a chain, the deleted BIO does not need to be at the end of a chain. The process of calling BIO_push() and BIO_pop() on a BIO may have additional consequences (a control call is made to the affected BIOs) any effects will be noted in the descriptions of individual BIOs. EXAMPLES
For these examples suppose md1 and md2 are digest BIOs, b64 is a base64 BIO and f is a file BIO. If the call: BIO_push(b64, f); is made then the new chain will be b64-chain. After making the calls BIO_push(md2, b64); BIO_push(md1, md2); the new chain is md1-md2-b64-f. Data written to md1 will be digested by md1 and md2, base64 encoded and written to f. It should be noted that reading causes data to pass in the reverse direction, that is data is read from f, base64 decoded and digested by md1 and md2. If the call: BIO_pop(md2); The call will return b64 and the new chain will be md1-b64-f data can be written to md1 as before. RETURN VALUES
BIO_push() returns the end of the chain, b. BIO_pop() returns the next BIO in the chain, or NULL if there is no next BIO. SEE ALSO
