I tried the dmraid tool on my Silicon Image raidcontroler and was able to query the metadata.
The metadata shown is correct for the logical volume.
lilith:/home/patrick# dmraid -r
/dev/hdi: sil, "sil_afajdfddahad", stripe, ok, 390718720 sectors, data@ 0
/dev/hdk: sil, "sil_afajdfddahad", stripe, ok, 390718720 sectors, data@ 0
lilith:/home/patrick# dmraid -s
*** Active Set
name : sil_afajdfddahad
size : 781437440
stride : 256
type : stripe
status : ok
devs : 2
spares : 0
Some funny things occure tho:
- After an fdisk I have to reboot to reload the partition table. My
guess is that this has to do with not calling the hardware directly but
using the devmapper.
- After an fsck 'df -hP' claims that 129MB is used. My question is; by
what? It's an empty partition with just the lost+found directory.
I also keep a log of my dmraid test activities and other stuff related
to dmraid on my website: http://lilith.cathedrallabs.org/dmraid/
Another question I have: The ChangeLog et all mention that LSI Logic's
Megaraid is supported. Does this also include the Megaraid used in Dell
poweredges and HP DL380s?
If the answer is yes to this question then I should be able to help out testing and trying things for this part aswell.
With kind regards, Patrick
