パッチ摘要: s700_800 11.11 128GBを超えるサイズへのJFS3.3ファイルシステムの拡張時のパニック
作成日: 07/02/22

ハードウェアプラットフォームおよびOSリリース:
s700: 11.11
s800: 11.11
現象:
PHKL_35933:
(SR:8606444177 CR:JAGag01754)
JFSファイルシステムを128GBより大きいサイズに拡張しようとすると、システ
ムが"dirty inval"でパニックになります。パニック時のスタックトレースは
次のようになっています。
panic+0x6c
brelse+0x224
vx_brelse_bp+0x38
vx_brelse_noflush+0x40
vx_brelse+0x74
vx_resize_sumcalc+0x544

vx_resize+0x52c
vx_aioctl_full+0xf8
vx_aioctl_common+0x3b4

問題点の説明:
PHKL_35933:
(SR:8606444177 CR:JAGag01754)
サイズ変更のためのエクステントマップのアップデート後ダーティsmapをフラ
ッシュしていなかったため、fsadm(1M)を使ってvxfsファイルシステムを128GB
より大きいサイズに拡張しようとすると、システムが"dirty inval"でパニッ
クになっていました。
解決方法:
サイズ変更のためのエクステントマップのアップデート後ダーティsmapを必ず
フラッシュするようにコードを修正しました。

System panics with 'dirty inval' when trying to extend a
JFS filesystem beyond 128GB. The panic stack trace will
be similar to:
panic+0x6c

Defect Description:
PHKL_35933:
( SR:8606444177 CR:JAGag01754 )
When trying to extend a vxfs filesystem beyond 128GB
using fsadm(1M), the system will panic with a 'dirty
inval' panic due to a failure to flush dirty smaps
after updating the extent maps for the resize.
Resolution:
We now ensure that any dirty smaps are flushed after
the extent maps are updated for resize.
Enhancement:
No
